fteqw/engine/server/sv_ents.c
Spoike fa9252cefa splitscreen cleaned up more. 
demo menu can now leave quake dir.
scissor+line rendering abstracted from csqc.
added a rain particle effect to the 'high' particle set.
added support for parsing ezquake's koi stuff. Still only generates utf-8.
implemented some string-buffer builtins from dp that have been stubs for quite some time.
http code now supports/uses gzipped downloads properly.
added support for non-blocking tcp connects.
#pragma optimize makes more sense with the gui version now.
