Added event handler service which.. handles events. More specifically, it $broadcasts events depending on their type, and does processing on events (shuffling keys, adding events to $rootScope so displays will automatically update, sending delivery receipts, and so on). Some of this logic was previously contained in the RoomController, which fails the moment you add >1 room into the mix, hence requiring a Service to handle events, rather than having each individual controller maintain their part of the world.
