More angular refactor

This PR will:

  - Allow us to add angular examples by just creating a controller file and loading the appropriate dependencies in `restful_angular_example_page`.
  - Fix the JSHint errors.
  - It will also fix properly https://github.com/Gizra/restful/commit/c54e852304b905b3b9362c8d246e1c868d6e5067 which only changed the `dist` file.
