Refactor Vue components using Composition API #230

- Migrate `StatefulVue`:
  - Introduce `UseCollectionState` that replaces its behavior and acts
    as a shared state store.
  - Add more encapsulated, granular functions based on read or write
    access to state in CollectionState.
- Some linting rules get activates due to new code-base compability to
  modern parses, fix linting errors.
  - Rename Dialog to ModalDialog as after refactoring,
    eslintvue/no-reserved-component-names does not allow name Dialog.
  - To comply with `vue/multi-word-component-names`, rename:
    - `Code`          -> `CodeInstruction`
    - `Handle`        -> `SliderHandle`
    - `Documentable`  -> `DocumentableNode`
    - `Node`          -> `NodeContent`
    - `INode`         -> `INodeContent`
    - `Responsive`    -> `SizeObserver`
- Remove `vue-property-decorator` and `vue-class-component`
  dependencies.
- Refactor `watch` with computed properties when possible for cleaner
  code.
  - Introduce `UseApplication` to reduce repeated code in new components
    that use `computed` more heavily than before.
- Change TypeScript target to `es2017` to allow top level async calls
  for getting application context/state/instance to simplify the code by
  removing async calls. However, mocha (unit and integration) tests do
  not run with top level awaits, so a workaround is used.
