Q3TA: Fixed script parsing, so the menus are not so broken.
Q3TA: added the UI_CIN_* and CG_CIN_* builtins for 2d cinematic playbacks.
Q3TA: backspace should work for gamecode text entry now.
Q3TA: map_restart now directly restarts without needing loading screens.
Fixed multiple envmap generation bugs.
Fixed envmaps getting flushed with r_keepimages 0.
Console image previews can now display cubemaps (although their orientation is probably a little off).
Made a 'remapshader' csqc builtin. Depending on the r_remapshader console command was stupid.
Fixed packet command to create a udp socket, if needed.
sv_public can now be set to a non-numeric name for custom names (instead of needing to poke sv_port too).
Support extended data on the end of miptex entries in bsps. Requires a qbsp (like vanilla) that doesn't rewrite the miptex entries.
Updated imgtool to generate/read our new extended miptex data.
