[Login screen fixes -- separate FBLogin button][Added class for managing user session, including the Otto eventbus library from square][Reduced complexity on the server by removing the temporary signup keys -- don't know why i did that honestly]

Next step: manage facebook login or server login in our user session manager, then add persistent storage of that information.
[EventBus upgrade in progress][FBLogin wired to UserSessionManager- code is 10x cleaner]

Next step: load registration info from event bus and populate accordingly.
