Add Actor::grab_key_focus() method

Browse Source 
Bug 1003 - Add clutter_actor_take_key_focus()

The grab_key_focus() method is just a simple wrapper around
clutter_stage_take_key_focus() that removes the need to get
the ClutterStage of an actor in order to set the key focus.

Based on a patch by Xan López.
