splitscreen can now properly be configured via build configs, and potentially more than just 4 seats. fix splitscreen and enemycolour forcing. forcing now works, but only when all seats are on/spectating the same team. fix demo playback issue with http urls with webgl that don't allow streaming. srgb fixes for the scoreboard. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5229 fc73d0e0-1445-4013-8a0c-d673dee63da5
