Spoike 9000f497ec misc fixes and tweaks: 
added //it stuffcmd.
now parsing //wps stuffcmds for ezhud use.
rework worker threads a little so that the main thread is no longer guaranteed to be stalled at least once. This speeds up load times a little.
fix nq server player counts in the server browser.
fix switching from/to spectator mode from destroying frag counts.
tweak custom bf args a little.
fix issue with player names starting with char 0x80.
fix menu.dat not loading.
attempt to fix flush lag on windows.
some fixes for stencil shadows.
try to fix public builds not knowing their svn revision. this should fix autoupdates.
added global_gravitydir vector, for mods that want to be really weird. doesn't clear onground flags however.
reworked the status command a little to attempt to report bursts a little better.
fix multicasts missing in mvds issue.
fix illegible server message with dpp7 downloads.
