game modules should use angular router

[7yl4r]

The controller/directive pairs used for game modules alongside $.show() and hide() are attempting to do routing, which is already a solved problem. Angular has a module which specifically addresses this. Benefits of switching to ng-router:

• standard architecture is more familiar with ng-devs
• navigate to any game module by modifying the url
• reduces DOM-clutter (better performance?)
• ???

To maintain existing functionality the listeners set up in the Nodule class would also have to be adapted to use $locationChangeStart or similar instead of $on('swtichToModule',... To maintain modularity, each new route should be declared in the module's controller rather than having all of them in the main application.
