Initial AngularJS structure

This contains some initial structure of the Angular-based frontend.
* It has been seeded with the 'angular-seed' template project, so there is not much genuine work in here ;)
* It contains the basic scaffolding for unit and end to end tests as well.

For now it just renders some hardcoded data.

Next steps:
* Adapt it to provide a view that talks to the backend via an actual API call
* Provide a real API endpoint in the backend so that we have a first complete end-to-end running system.
