Simplify test-cogl-primitives
This removes a lot of code from test-cogl-primitives to make it easier to follow. The TestCoglBox custom actor has gone and instead a blank ClutterGroup is created with a paint signal handler. Instead of rendering constantly and updating when a GTimer elapses a second, a ClutterTimeline is used with 1 fps and a new redraw is queued every frame. The custom main loop is replaced with a regular call to clutter_main. This fixes the close button of the stage window so you can quit without having to press Ctrl+C.
