Add symbolic constants for event propagation

Browse Source 
I always have to think twice before returning a value from an event
signal handler, and I've been writing them for the past 10 years, so
it's conceivable that application developers that start with Clutter
will find them confusing as well.

Simple symbolic names should be easier to use.
