The current dialog APIs make it possible to register for fine grained events on a particular DialogContext, but not on events from DialogContextManager. In particular, it is not currently possible to be notified when a new DialogContext instance is created via navigation. Address this by adding eventing to DialogContextManager along the following lines:
* New DialogContextManagerListener interface with onCreate() and onRemove() methods
* New AbstractDialogContextManager that implements the listener registration stuff
(analogous to AbsractDialogContext for context level event)
* Modify the two DialogContextManager implementations to extend this new base class
and to call the event firing methods at the right times
* Unit tests for all of the above (of course :-)
* For naming consistency, consider renaming DialogListener to DialogContextListener
and associated ripple effects. We can minimize transition impacts on current apps
by leaving a deprecated DialogListener interface that simply extends DialogContextListener
(and so on).
