We want to use onDestroyView for unregistering observers after all
readability, fixed main layout
Native elation event bridge working (need to call elationNative.bridgeEvent(event) from js)

ElationEventObserver can register any object to an event name (or class name) for notification

Added demonstration classes for standard Java implementation and Intent implemenation of native Elation Event handlers
Better comments, logging set to debug
Renamed (again!) ElationEventObservable to ElationEventManager to more accurately reflect its function

Cleaned up ElationEventManager's API a bit
Merge pull request #3 from Zanshinmu/master

JS Bridge functional, AdapterObservable generalized to ElationEventObservable, provides methods to register/unregister Observers and send/register intents
