From: Darrell Walisser <dwaliss1@purdue.edu>
Subject: Patch for video bugs + Max's additions
I've attached a patch for today's CVS that includes Max's virtual
mouse button fix as well as some other changes:
-building mode list correctly now (had duplicate entries, was unsorted)
-switching modes correctly now (wasn't destroying previous mode)
-releasing memory correctly in event loop
