5721e754a6
Fix a number of gles2 bugs. Fix infoblobs. they should be much more reliable now. Added callbacks so csqc can know when serverinfo|playerinfo changes (at least for processing blob changes anyway). Fix 'pkg addsource' not saving (and remsource). git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5475 fc73d0e0-1445-4013-8a0c-d673dee63da5
