Fix prediction issues with the ftenq protocol. Fix some console image previews. Added mod_precache cvar. set to 0 to significantly reduce memory usage in xonotic... Prevent xonotic's random file writes from forcing full worker syncs, for faster loading. QTV connections are now accepted only from localhost peers by default. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5694 fc73d0e0-1445-4013-8a0c-d673dee63da5
