[SP] Go back to eez's way of doing buttons (but correctly, map them).
Read: it goes from XINPUT_GAMEPAD_RIGHT_SHOULDER (0x0200) to #define XINPUT_GAMEPAD_A (0x1000) and the guide button is sneaky at 0x0400
The buttons are still flakey with being randomly held down though.

[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.
