* clutter/clutter-actor.c: Implement part of the ClutterScriptable
	interface, using the ClutterActor API to set and get the name
	of an actor.

	(clutter_geometry_copy), (clutter_geometry_free): Use
	the slice allocator to avoid fragmentation when setting
	properties and emitting signals (that is: when packing
	boxed types into GValues).

	(clutter_actor_box_copy), (clutter_actor_box_free),
	(clutter_vertex_copy), (clutter_vertex_free): Ditto.

	* clutter/clutter-actor.h:
	* clutter/clutter-actor.c:
	(clutter_actor_push_transform_child),
	(clutter_actor_pop_transfomr_child): Simple wrappers around
	COGL API, which avoid including clutter/cogl.h when writing
	container actors outside Clutter.
