timeline: Deprecate the clone() method

Browse Source 
The clutter_timeline_clone() method was a pretty dumb idea when it was
introduced, back when we still had the ClutterEffectTemplate and the
clutter_effect_* animation API. It has since become an API wart: we
cannot change or add new properties to be cloned without the risk of
breaking existing code. All in all, cloning a GObject is just a matter
of calling g_object_new() with the wanted properties.

Let's deprecate this throwback of the Olden Days™, so that we can remove
it for good once we break for 2.0.
