added markers for spliting head from weapon tracking, added weaponangle to ucmd
most of multiple tracking code in place, still need static write target to be ddevice specific
recoded to work with multiple trackers and hot plug & unplug
now supports multiple trackers
separate weapon tracking now functional all the way down to specifying the angle ngl fire angle, which appears to be mapped differently
tweaking viewmodel rotations & movements to fit with tracker movements... still tbd, also switched calibration to only calibrate yaw
adding new installer stuff
more on installer, basic framing all done now
added gamepad support (tho still oddly jerky) for yaw, cleaned up console vars and added ability to invert each axis
