* clutter/clutter-marshal.list: Add signature for the
	::marker-reached signal marshaller.

	* clutter/clutter-timeline.[ch]: Add timeline marker API;
	using markers it is possible to add a unique identifier to
	a particular frame of the timeline, and receive a signal
	notification when reaching that particular marker while
	playing the timeline. (#641)

	* tests/test-timeline.c: Update the test case to check for
	the marker-reached signal emission.

	* clutter.symbols: Add new symbols.
