[MP] Suppress "WARNING: CM_GridPlane unresolvable" message.
Added cm_extraVerbose cvar to enable it for development.  Does not save to config, must be explicitly set before map load.
[MP] in_disablemacosxmouseaccel was unused, removing.
[SP] in_disablemacosxmouseaccel was unused, removing.
first pass on automatically recording server-side demos.

setting sv_autoDemo 1 will enable.  you must explicitly set sv_autoDemoBots
1 to save bot demos automatically.  auto-demoing will interfere with manual
demoing, so don't mix the two.

the demos are grouped into a single folder per map + time map started.
optionally, set sv_autoDemoMaxMaps to automatically delete demos from more than N maps ago.
