Prettier support

[sinedied]

Prettier is a nice automated code formatter supporting TypeScript and Sass, with experimental HTML support.

This is a very good candidate for an optional add-on, that would come preconfigured with pre-commit hook using husky, and default configuration compatible with the generator tslint.json config.

npm install pretty-quick husky --save-dev
Then edit package.json:

{
  "scripts": {
    "precommit": "pretty-quick --staged"
  }
}
