Subject: 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.
