window-actor: add new signal "effects-completed"

Browse Source 
When using plugins, the effects will affect the MetaWindowActor size
and position.

Add a new signal "effects-completed" wired to the corresponding
MetaWindowActor which is emitted when all effects are completed so that
derived objects can be notified when all effects are completed and use
the actual size and position.
