WIP: Angularify lobby

This is under :construction: 

Sending PR to start the conversation on this adventure.

This is a :baby_symbol: step towards the :moneybag: 

- [ ] Our implementation of internationalization of text doesn't run (as it's no longer a Razor file)
- [ ] Search / Filter
- [ ] Updating when changes occur
- [ ] Split app/controllers/directives etc into their own files

It's a start, let's discuss it and make sure we make it a success :sparkling_heart:
