Added base for frontend development:
	* decided on Phaser in the end (gives some good abstractions over tiled map and there are tons of tutorials)
	* for now using bower for dependencies (see bower.json file)
	* each squad will create its own angular module which we can then add in app.js to modules seen (and to angularRoute so it sees the partial HTMLs)
	* for now using base Bootstrap css, we can always generate one with custom colours
