Partial timer cleanup

After this revision, the only place timerUpdate() is called is from within handleevents(). S_Cleanup(), MUSIC_Update(), and G_HandleSpecialKeys() are now called from a timer callback set with timerSetCallback(). This more or less deprecates the usage of faketimerhandler() in EDuke32 and Mapster32, but other games still rely on the functionality.
