* clutter/sdl/clutter-backend-sdl.c:
	(clutter_backend_sdl_dispose): Destroy the timer that we created...
	(clutter_backend_sdl_init): ... here.

	* clutter/sdl/clutter-backend-sdl.h: Add a GTimer for time-based
	operations, like the event time.

	* clutter/sdl/clutter-event-sdl.c:
	(get_backend_time): Get the elapsed milliseconds for the SDL
	backend.

	(_clutter_events_init): Start the timer provided by the backend...
	(_clutter_events_uninit): ... and the stop it.

	(key_event_translate), (event_translate): Use the backend time
	to fill out the time field of the event structures. This fixes
	the motion notification throttling on the SDL backend.
