This commit fixes two issues:
a. Fix `npm install` not working
b. Fix building not working after npm install fix.
npm install fails with dependency resolution issue due to Vue CLI as
following:
```txt
npm ERR! code ERESOLVE
npm ERR! ERESOLVE could not resolve
npm ERR!
npm ERR! While resolving: cache-loader@4.1.0

```txt
As suggested in Vue issues regenerating packages-lock.json solves the
issue, see: vuejs/vue-cli#6793, vuejs/vue-cli#7095.
However with the new package-lock.json a Font Awesome dependency issue
breaks the builds such as the following:
```txt
ERROR in src/presentation/bootstrapping/Modules/IconBootstrapper.ts:17:7
TS2345: Argument of type 'IconDefinition' is not assignable to parameter of type 'IconDefinitionOrPack'.
Type 'IconDefinition' is not assignable to type 'IconPack'.
Index signature for type 'string' is missing in type 'IconDefinition'.

```
This is solved by adding a patch in `tsconfig.json`. This issue was
discussed in FortAwesome/Font-Awesome#12575 where the workaround was
recommended.
Unify definition of aliases in single place.
Make TypeScript configuration file (`tsconfig.json`) source of truth
regarding aliases.
Both webpack (through `vue.config.js`) and ESLint (through
`.eslintrc.js`) now reads the alias configuration from `tsconfig.json`.
- Use function abstractions (such as map, reduce, filter etc.) over
for-of loops to gain benefits of having less side effects and easier
readability.
- Enable `downLevelIterations` for writing modern code with lazy evaluation.
- Refactor for of loops to named abstractions to clearly express their
intentions without needing to analyse the loop itself.
- Add missing cases for changes that had no tests.
Alias would remove unnecessary repetitions and less relative paths make changes easier when moving around files. This commit cleans also up some relative paths ('../../../') by using the alias and orders imports. It updates both path alias in tsconfig and module alias in Vue CLI's bundler (vuejs/vue-cli#2398).
