Bump dependencies to latest

Purge unused dependencies.

Update dependencies to latest except:

- ts-lint. Keep locked to 9.0.1 because that's the latest version that
  works with Webpack 4 that's still used by
  vue-cli-plugin-electron-builder.
- Keep eslint at version 7 because tests cannot be run/compiled with
  version 7, see eslint/eslint#15678, vuejs/vue-cli#6759.

Newer versions of ESLint modules do not allow linebreak after or before
= operator (operator-linebreak). This commit also changes files to
comply with it.

Closes #116, #119, #122, #130.

-## Pull Request Process
+- reporting a bug,
+- discussing the current state of the code,
+- submitting a fix,
+- proposing new features,
+- or becoming a maintainer.
 
-- [GitHub flow](https://guides.github.com/introduction/flow/index.html) is used
+As a small open source project with small community, it can sometimes take a long time to address the issues so please be patient.
-- Your pull requests are actively welcomed.
+
-- The steps:
+## Pull request process
-  1. Fork the repo and create your branch from master.
+
-  2. If you've added code that should be tested, add tests.
+Your pull requests are actively welcomed. We collaborate using [GitHub flow](https://docs.github.com/en/get-started/quickstart/github-flow).
-  3. If you've changed APIs, update the documentation.
+
-  4. Ensure the test suite passes.
+The steps:
-  5. Make sure your code lints.
+
-  6. Issue that pull request!
+1. Fork the repo and create your branch from master.
-- 🙏 DO
+2. If you've added code that requires testing, add tests. See [tests.md](./docs/tests.md).
-  - Document your changes in the pull request
+3. If you've done a major change, update the documentation. See [docs/](./docs/).
-- ❗ DON'T
+4. Ensure the test suite passes. See [development.md | Testing](./docs/development.md#testing) for commands.
-  - Do not update the versions, current version is only [set by the maintainer](./img/architecture/gitops.png) and updated automatically by [bump-everywhere](https://github.com/undergroundwires/bump-everywhere)
+5. Make sure your code lints.See [development.md | Linting](./docs/development.md#linting) for commands.
+6. Issue that pull request!
+
+**🙏 DO:**
+
+- Document why (what you're trying to solve) rather than what in the pull request.
+
+**❗ DON'T:**
+
+- Do not update the versions, current version is [set by the maintainer](./docs/ci-cd.md#gitops) and updated automatically by [bump-everywhere](https://github.com/undergroundwires/bump-everywhere).
+
+Automated pipelines will run to control your PR and they will publish your code once the maintainer merges your PR.
+
+📖 You can read more in [ci-cd.md](./docs/ci-cd.md).
+
+## Extend scripts
+
+Here's quick information for you who want to add more scripts.
+
+You have two alternatives:
+
+1. [Create an issue](https://github.com/undergroundwires/privacy.sexy/issues/new/choose) and ask for someone else to add the script for you.
+2. Or send a PR yourself. This would make it faster to get your code into the project. You need to add scripts to related OS in [collections](src/application/collections/) folder. Then you'd sent a pull request, see [pull request process](#pull-request-process).
+   - 📖 If you're unsure about the syntax, check [collection-files.md](docs/collection-files.md).
+   - 📖 If you wish to use templates, use [templating.md](./docs/templating.md).

 # Application
 
-- It's mainly responsible for
+Application layer is mainly responsible for:
-  - creating and event based [application state](#application-state)
+
-  - parsing and compiling [application data](#application-data)
+- creating an event-based and mutable [application state](#application-state),
+- [parsing and compiling](#parsing-and-compiling) the [application data](#application-data).
+
+📖 Refer to [architecture.md | Layered Application](./architecture.md#layered-application) to read more about the layered architecture.
+
+## Structure
+
+Application layer code exists in [`/src/application`](./../src/application/) and includes following structure:
+
+- [**`collections/`**](./../src/application/collections/): Holds [collection files](./collection-files.md).
+- [**`Common/`**](./../src/application/Common/): Contains common functionality in application layer.
+- `...`: rest of the application layer source code organized using folders-by-feature structure.
 
 ## Application state
 
-- [ApplicationContext.ts](./../src/application/Context/ApplicationContext.ts) holds the [CategoryCollectionState](./../src/application/Context/State/CategoryCollectionState.ts) for each OS
+It uses [state pattern](https://en.wikipedia.org/wiki/State_pattern) with context and state objects. [`ApplicationContext.ts`](./../src/application/Context/ApplicationContext.ts) the "Context" of state pattern provides an instance of [`CategoryCollectionState.ts`](./../src/application/Context/State/CategoryCollectionState.ts) (the "State" of the state pattern) for every supported collection.
-- Uses [state pattern](https://en.wikipedia.org/wiki/State_pattern)
+
-- Same instance is shared throughout the application to ensure consistent state
+Presentation layer uses a singleton (same instance of) [`ApplicationContext.ts`](./../src/application/Context/ApplicationContext.ts) throughout the application to ensure consistent state.
-- 📖 See [Application State | Presentation layer](./presentation.md#application-state) to read more about how the state should be managed by the presentation layer.
+
-- 📖 See [ApplicationContext.ts](./../src/application/Context/ApplicationContext.ts) to start diving into the state code.
+📖 Refer to [architecture.md | Application State](./architecture.md#application-state) to get an overview of event handling and [presentation.md | Application State](./presentation.md#application-state) for deeper look into how the presentation layer manages state.
 
 ## Application data
 
-- Compiled to `Application` domain object.
+Application data is collection files using YAML. You can refer to [collection-files.md](./collection-files.md) to read more about the scheme and structure of application data files. You can also check the source code [collection yaml files](./../src/application/collections/) to directly see the application data using that scheme.
-- The scripts are defined and controlled in different data files per OS
+
-- Enables [data-driven programming](https://en.wikipedia.org/wiki/Data-driven_programming) and easier contributions
+Application layer [parses and compiles](#parsing-and-compiling) application data into [`Application`](./../src/domain/Application.ts)). Once parsed, application layer provides the necessary functionality to presentation layer based on the application data. You can read more about how presentation layer consumes the application data in [presentation.md | Application Data](./presentation.md#application-data).
-- Application data is defined in collection files and
+
-- 📖 See [Application data | Presentation layer](./presentation.md#application-data) to read how the application data is read by the presentation layer.
+Application layer enables [data-driven programming](https://en.wikipedia.org/wiki/Data-driven_programming) by leveraging the data to the rest of the source code. It makes it easy for community to contribute on the project by using a declarative language used in collection files.
-- 📖 See [collection files documentation](./collection-files.md) to read more about how the data files are structured/defined and see [collection yaml files](./../src/application/collections/) to directly check the code.
+
+### Parsing and compiling
+
+Application layer parses the application data to compile the domain object [`Application.ts`](./../src/domain/Application.ts).
+
+A webpack loader loads (or injects) application data ([collection yaml files](./../src/application/collections/)) into the application layer in compile time. Application layer ([`ApplicationFactory.ts`](./../src/application/ApplicationFactory.ts)) parses and compiles this data in runtime.
+
+Application layer compiles templating syntax during parsing to create the end scripts. You can read more about templating syntax in [templating.md](./templating.md) and how application data uses them through functions in [collection-files.md | Function](./collection-files.md#function).
+
+The steps to extend the templating syntax:
+
+1. Add a new parser under [SyntaxParsers](./../src/application/Parser/Script/Compiler/Expressions/SyntaxParsers) where you can look at other parsers to understand more.
+2. Register your in [CompositeExpressionParser](./../src/application/Parser/Script/Compiler/Expressions/Parser/CompositeExpressionParser.ts).

+# Architecture overview
+
+This repository consists of:
+
+- A [layered application](#layered-application).
+- [AWS infrastructure](#aws-infrastructure) as code and instructions to host the website.
+- [GitOps](#gitops) practices for development, maintenance and deployment.
+
+## Layered application
+
+Application is
+
+- powered by **TypeScript**, **Vue.js** and **Electron** 💪,
+- and driven by **Domain-driven design**, **Event-driven architecture**, **Data-driven programming** concepts.
+
+Application uses highly decoupled models & services in different DDD layers:
+
+- presentation layer (see [presentation.md](./presentation.md)),
+- application layer (see [application.md](./application.md)),
+- and domain layer.
+
+Application layer depends on and consumes domain layer. [Presentation layer](./presentation.md) consumes and depends on application layer along with domain layer. Application and presentation layers can communicate through domain model.
+
+![DDD + vue.js](./../img/architecture/app-ddd.png)
+
+### Application state
+
+State handling uses an event-driven subscription model to signal state changes and special functions to register changes. It does not depend on third party packages.
+
+Each layer treat application layer differently.
+
+![State](./../img/architecture/app-state.png)
+
+*[Presentation layer](./presentation.md)*:
+
+- Each component holds their own state about presentation-related data.
+- Components register shared state changes into application state using functions.
+- Components listen to shared state changes using event subscriptions.
+- 📖 Read more: [presentation.md | Application state](./presentation.md#application-state).
+
+*[Application layer](./application.md)*:
+
+- Stores the application-specific state.
+- The state it exposed for read with getter functions and set using setter functions, setter functions also fire application events that allows other parts of application and the view in presentation layer to react.
+- So state is mutable, and fires related events when mutated.
+- 📖 Read more: [application.md | Application state](./application.md#application-state).
+
+It's comparable with flux ([`redux`](https://redux.js.org/)) or flux-like ([`vuex`](https://vuex.vuejs.org/)) patterns. Flux component "view" is [presentation layer](./presentation.md) in Vue. Flux functions "dispatcher", "store" and "action creation" functions lie in the [application layer](./application.md). A difference is that application state in privacy.sexy is mutable and lies in single flux "store" that holds app state and logic. The "actions" mutate the state directly which in turns act as dispatcher to notify its own event subscriptions (callbacks).
+
+## AWS infrastructure
+
+The web-site runs on serverless AWS infrastructure. Infrastructure is open-source and deployed as code. [aws-static-site-with-cd](https://github.com/undergroundwires/aws-static-site-with-cd) project includes the source code.
+
+[![AWS solution](../img/architecture/aws-solution.png)](https://github.com/undergroundwires/aws-static-site-with-cd)
+
+The design priorities highest security then minimizing cloud infrastructure costs.
+
+This project includes [GitHub Actions](../.github/workflows/) to automatically provision the infrastructure with zero-touch and without any "hidden" steps, ensuring everything is open-source and transparent. Git repositories includes all necessary instructions and automation with [GitOps](#gitops) practices.
+

+# CI/CD overview
+
+## GitOps
+
+CI/CD is fully automated using different Git events and GitHub actions. This repository uses [bump-everywhere](https://github.com/undergroundwires/bump-everywhere) to automate versioning, tagging, creation of `CHANGELOG.md` and GitHub releases. A dedicated workflow [release.desktop.yaml](./../.github/workflows/release.desktop.yaml) creates desktop installers and executables and attaches them into GitHub releases.
+
+Everything that's merged in the master goes directly to production.
+
+[![CI/CD using GitHub Actions](./../img/architecture/gitops.png)](../.github/workflows/)
+
+## Pipeline files
+
+privacy.sexy uses [GitHub actions](https://github.com/features/actions) to define and run pipelines as code.
+
+GitHub workflows i.e. pipelines exist in [`/.github/workflows/`](./../.github/workflows/) folder without any subfolders due to GitHub actions requirements [1] .
+
+Local GitHub actions are defined in [`/.github/actions/`](./../.github/actions/) and used to reuse same workflow steps.
+
+## Pipeline types
+
+We categorize pipelines into different categories. We use these names in convention when naming files and actions, see [naming conventions](#naming-conventions).
+
+The categories consist of:
+
+- `tests`: Different types of tests to verify functionality.
+- `checks`: Other controls such as vulnerability scans or styling checks.
+- `release`: Pipelines used for release of deployment such as building and testing.
+
+## Naming conventions
+
+Convention for naming pipeline files: **`<type>.<name>.yaml`**.
+
+**`type`**:
+
+- Sub-folders do not work for GitHub workflows [1] so we use `<type>.` prefix to organize them.
+- See also [pipeline types](#pipeline-types) for list of all usable types.
+
+**`name`**:
+
+- We name workflows using kebab-case.
+- E.g. file name `tests.unit.yaml`, pipeline file should set the naem as: `name: unit-tests`.
+- Kebab-case allows to have better URL references to them.
+  - [README.md](./../README.md) uses URL references to show status badges for actions.

+Components (should) use [ApplicationFactory](./../src/application/ApplicationFactory.ts) singleton to reach the application domain to avoid [parsing and compiling](./application.md#parsing-and-compiling) the application again.

+
-  - available scripts, collections as defined in [collection files](./collection-files.md)
+[Application.ts](../src/domain/Application.ts) is an immutable domain model that represents application state. It includes:

+- available scripts, collections as defined in [collection files](./collection-files.md),
+- package information as defined in [`package.json`](./../package.json).
+
+You can read more about how application layer provides application data to he presentation in [application.md | Application data](./application.md#application-data).
 
 ## Application state
 
-- Stateful components mutate or/and react to state changes in [ApplicationContext](./../src/application/Context/ApplicationContext.ts).
+Inheritance of a Vue components marks whether it uses application state . Components that does not handle application state extends `Vue`. Stateful components mutate or/and react to state changes (such as user selection or search queries) in [ApplicationContext](./../src/application/Context/ApplicationContext.ts) extend [`StatefulVue`](./../src/presentation/components/Shared/StatefulVue.ts) class to access the context / state.
-- Stateless components that does not handle state extends `Vue`
+
-- Stateful components that depends on the collection state such as user selection, search queries and more extends [`StatefulVue`](./../src/presentation/StatefulVue.ts)
+[`StatefulVue`](./../src/presentation/components/Shared/StatefulVue.ts) functions include:
-- The single source of truth is a singleton of the state created and made available to presentation layer by [`StatefulVue`](./../src/presentation/StatefulVue.ts)
+
-- `StatefulVue` includes abstract `handleCollectionState` that is fired once the component is loaded and also each time [collection](./collection-files.md) is changed.
+- Creating a singleton of the state and makes it available to presentation layer as single source of truth.
-- Do not forget to subscribe from events when component is destroyed or if needed [collection](./collection-files.md) is changed.
+- Providing virtual abstract `handleCollectionState` callback that it calls when
-  - 💡 `events` in base class [`StatefulVue`](./../src/presentation/StatefulVue.ts) makes lifecycling easier
+  - the Vue loads the component,
-- 📖 See [Application state | Application layer](./presentation.md#application-state) where the state is implemented using using state pattern.
+  - and also every time when state changes.
+- Providing `events` member to make lifecycling of state subscriptions events easier because it ensures that components unsubscribe from listening to state events when
+  - the component is no longer used (destroyed),
+  - an if [ApplicationContext](./../src/application/Context/ApplicationContext.ts) changes the active [collection](./collection-files.md) to a different one.
+
+📖 Refer to [architecture.md | Application State](./architecture.md#application-state) to get an overview of event handling and [application.md | Application State](./presentation.md#application-state) for deeper look into how the application layer manages state.
+
+## Modals
+
+[Dialog.vue](./../src/presentation/components/Shared/Dialog.vue) is a shared component that other components used to show modal windows.
+
+You can use it by wrapping the content inside of its `slot` and call `.show()` function on its reference. For example:
+
+  ```html
+    <Dialog ref="testDialog">
+      <div>Hello world</div>
+    </Dialog>
+    <div @click="$refs.testDialog.show()">Show dialog</div>
+  ```
+
+## Sass naming convention
+
+- Use lowercase for variables/functions/mixins, e.g.:
+  - Variable: `$variable: value;`
+  - Function: `@function function() {}`
+  - Mixin: `@mixin mixin() {}`
+- Use - for a phrase/compound word, e.g.:
+  - Variable: `$some-variable: value;`
+  - Function: `@function some-function() {}`
+  - Mixin: `@mixin some-mixin() {}`
+- Grouping and name variables from generic to specific, e.g.:
+  - ✅ `$border-blue`, `$border-blue-light`, `$border-blue-lightest`, `$border-red`
+  - ❌ `$blue-border`, `$light-blue-border`, `$lightest-blue-border`, `$red-border`

+# Templating
+
+## Benefits of templating
+
+- Generating scripts by sharing code to increase best-practice usage and maintainability.
+- Creating self-contained scripts without cross-dependencies.
+- Use of pipes for writing cleaner code and letting pipes do dirty work.
+
+## Expressions
+
+- Expressions start and end with mustaches (double brackets, `{{` and `}}`).
+  - E.g. `Hello {{ $name }} !`
+- Syntax is close to [Go Templates ❤️](https://pkg.go.dev/text/template) that has inspired this templating language.
+- Functions enables usage of expressions.
+  - In script definition parts of a function, see [`Function`](./collection-files.md#Function).
+  - When doing a call as argument values, see [`FunctionCall`](./collection-files.md#Function).
+
+### Parameter substitution
+
+A simple function example:
+
+```yaml
+  function: EchoArgument
+  parameters:
+    - name: 'argument'
+  code: Hello {{ $argument }} !
+```
+
+It would print "Hello world" if it's called in a [script](./collection-files.md#script) as following:
+
+```yaml
+  script: Echo script
+  call:
+    function: EchoArgument
+    parameters:
+      argument: World
+```
+
+A function can call other functions such as:
+
+```yaml
+  - 
+    function: CallerFunction
+    parameters:
+      - name: 'value'
+    call:
+      function: EchoArgument
+      parameters:
+        argument: {{ $value }}
+  -
+    function: EchoArgument
+    parameters:
+      - name: 'argument'
+    code: Hello {{ $argument }} !
+```
+
+### with
+
+Skips its "block" if the variable is absent or empty. Its "block" is between `with` start (`{{ with .. }}`) and end (`{{ end }`}) expressions. E.g. `{{ with $parameterName }} Hi, I'm a block! {{ end }}`.
+
+Binds its context (`.`) value of provided argument for the parameter if provided one. E.g. `{{ with $parameterName }} Parameter value is {{ . }} here {{ end }}`.
+
+💡 Declare parameters used for `with` condition as optional. Set `optional: true` for the argument if you use it like `{{ with $argument }} .. {{ end }}`.
+
+Example:
+
+```yaml
+  function: FunctionThatOutputsConditionally
+  parameters:
+    - name: 'argument'
+      optional: true
+  code: |- 
+    {{ with $argument }}
+      Value is: {{ . }}
+    {{ end }}
+```
+
+### Pipes
+
+- Pipes are functions available for handling text.
+- Allows stacking actions one after another also known as "chaining".
+- Like [Unix pipelines](https://en.wikipedia.org/wiki/Pipeline_(Unix)), the concept is simple: each pipeline's output becomes the input of the following pipe.
+- You cannot create pipes. [A dedicated compiler](./application.md#parsing-and-compiling) provides pre-defined pipes to consume in collection files.
+- You can combine pipes with other expressions such as [parameter substitution](#parameter-substitution) and [with](#with) syntax.
+- ❗ Pipe names must be camelCase without any space or special characters.
+- **Existing pipes**
+  - `inlinePowerShell`: Converts a multi-lined PowerShell script to a single line.
+  - `escapeDoubleQuotes`: Escapes `"` characters, allows you to use them inside double quotes (`"`).
+- **Example usages**
+  - `{{ with $code }} echo "{{ . | inlinePowerShell }}" {{ end }}`
+  - `{{ with $code }} echo "{{ . | inlinePowerShell | escapeDoubleQuotes }}" {{ end }}`

+# Tests
+
+There are different types of tests executed:
+
+1. [Unit tests](#unit-tests)
+2. [Integration tests](#integration-tests)
+3. [End-to-end (E2E) tests](#e2e-tests)
+
+Common aspects for all tests:
+
+- They use [Mocha](https://mochajs.org/) and [Chai](https://www.chaijs.com/).
+- Their files end with `.spec.{ts|js}` suffix.
+
+💡 You can use path/module alias `@/tests` in import statements.
+
+## Unit tests
+
+- Unit tests test each component in isolation.
+- All unit tests goes under [`./tests/unit`](./../tests/unit).
+- They rely on [stubs](./../tests/unit/shared/Stubs) for isolation.
+
+### Unit tests structure
+
+- [`./src/`](./../src/)
+  - Includes source code that unit tests will test.
+- [`./tests/unit/`](./../tests/unit/)
+  - Includes test code.
+  - Tests follow same folder structure as [`./src/`](./../src).
+    - E.g. if system under test lies in [`./src/application/ApplicationFactory.ts`](./../src/application/ApplicationFactory.ts) then its tests would be in test would be at [`./tests/unit/application/ApplicationFactory.spec.ts`](./../tests/unit/application/ApplicationFactory.spec.ts).
+  - [`shared/`](./../tests/unit/shared/)
+    - Includes common functionality that's shared across unit tests.
+    - [`Assertions/`](./../tests/unit/shared/Assertions):
+      - Common assertions that extend [Chai Assertion Library](https://www.chaijs.com/).
+      - Asserting functions should start with `expect` prefix.
+    - [`TestCases/`](./../tests/unit/shared/TestCases/)
+      - Shared test cases.
+      - Functions that calls `it()` from [Mocha test framework](https://mochajs.org/) should have `it` prefix.
+        - E.g. `itEachAbsentCollectionValue()`.
+    - [`Stubs/`](./../tests/unit/shared/Stubs)
+      - Includes stubs to be able to test components in isolation.
+      - Stubs have minimal and dummy behavior to be functional, they may also have spying or mocking functions.
+
+### Unit tests naming
+
+- Each test suite first describe the system under test.
+  - E.g. tests for class `Application.ts` are all inside `Application.spec.ts`.
+- `describe` blocks tests for same function (if applicable).
+  - E.g. test for `run()` are inside `describe('run', () => ..)`.
+
+### Act, arrange, assert
+
+- Tests use act, arrange and assert (AAA) pattern when applicable.
+- **Arrange**
+  - Sets up the test case.
+  - Starts with comment line `// arrange`.
+- **Act**
+  - Executes the actual test.
+  - Starts with comment line `// act`.
+- **Assert**
+  - Elicit some sort of expectation.
+  - Starts with comment line `// assert`.
+
+## Integration tests
+
+- Tests functionality of a component in combination with others (not isolated).
+- Ensure dependencies to third parties work as expected.
+- Defined in [./tests/integration](./../tests/integration).
+
+## E2E tests
+
+- Test the functionality and performance of a running application.
+- Vue CLI plugin  [`e2e-cypress`](https://github.com/vuejs/vue-cli/tree/dev/packages/@vue/cli-plugin-e2e-cypress#readme) configures E2E tests.
+- Test names and folders have logical structure based on tests executed.
+- The structure is following:
+  - [`cypress.json`](./../cypress.json): Cypress configuration file.
+  - [`./tests/e2e/`](./../tests/e2e/): Base Cypress folder.
+    - [`/specs/`](./../tests/e2e/specs/): Test files named with `.spec.js` extension.
+    - [`/plugins/index.js`](./../tests/e2e/plugins/index.js): Plugin file executed before loading project.
+    - [`/support/index.js`](./../tests/e2e/support/index.js): Support file, runs before every single spec file.
+    - *(Ignored)* `/videos`: Asset folder for videos taken during tests.
+    - *(Ignored)* `/screenshots`: Asset folder for Screenshots taken during tests.
