allow for binary updates on linux as on windows (-allowupdate for modified/nonsvn builds). dlightmask is now size_t, because we might as well allow that on 64bit cpus, this allows for 64 lightmaphack lights instead of 32. fix potential openal issue with source=0. added q3bsp_ignorestyles cvar to ignore rbsp styles (and reduce needed batch counts), should only be used on maps with subtle lighting changes (ones that are properly lit without toggling any lightswitches). add support for directly loading foo.bsp.gz Added prints to clarify why servers might be listed under the 'UNKNOWN' category in the master server. Attempt to show hostnames anyway, to make it a little more obvious who's responsible for those badly configured servers. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5656 fc73d0e0-1445-4013-8a0c-d673dee63da5
