Spoike 9360a016c2 mvd: cl_autotrack_team cvar locks autotrack to a specific team. getting the team name to match can still be problematic when it contains non-ascii chars however. 
qw: fix recording mid-map.
q2: add support for recording demos on q2 servers.
q: fix setattachment not using the correct orientations.
q2: now supports splitscreen, as well as increased model and sound limits.
cl: fix crosshair not appearing in splitscreen.
cl: splitscreen clients now get their own colour tints (like the bf command)
snd: tweak audio to be a bit more usable in splitscreen by default.
cl: added con_logcenterprint cvar, for shoving a copy of centerprints onto the console. by default only appears in single player.
qc: add checkbuiltin builtin. for all those #0 builtins without their own extension name.
gl: fix r_dynamic -1 bug that was painfully visible in AD.
mdl: validate per-frame bounds of mdl files (stuff that would crash software renderers).
sv: fix -port or +sv_port commandline args to override the port correctly.
win: attempt to cope with windows symlinks enumerating with the wrong filesizes.
gl: fix skyboxes not appearing properly.
gl: fix sprite alpha/edge issue resulting in some invisible sprites in AD.
gl: fix screenshot_mega, in combination with r_projection. yay for HUGE panoramic screenshots.
q2: fix replacement textures issue.
qw: fix download demonum/X issue, both in client and server.
qw: fix multicast dimensions not always being honoured properly.
nq: fix starting angles sometimes being wrong.
menusys: I'm finally uploading my menusys library, plus example mod, which I'll now be providing like csaddon is.
