* clutter/clutter-timeline.[ch]: Added ClutterTimeline:duration,
	a property for setting the duration of a timeline in milliseconds.
	The property comes with accessors and a new constructor. The
	frame rate used is the default value.

	* clutter/clutter-private.h:
	* clutter/clutter-main.[ch]: Add clutter_get_default_frame_rate()
	and clutter_set_default_frame_rate(); these two functions control
	the default frame rate to be used when creating timelines. Currently
	is set to 60 frames-per-second.
