Minor code reformatting, some code simplification.
Changed some USEREVENT numbers around as I'm not sure that USEREVENT + 8 will ever get triggered.
More minor code reformatting and simplification.
Fixed bug where no new song would start after first song ended (in game).
Added clocks and clock ticks to Start/Help/Options pages as I noticed the game was chewing cpu when idle on those pages.  Also some minor code reformatting.
