Added way to disable crouch and jump in turn axis.

I accidentally jumped with the Hydra, not sure it will happen with the
Touch, but just in case I made crouch and jump optional.

Command To Log Devices

Useful for helping understand a users system.

Experimental Holster Slot

Now you can holster a weapon on your right hip, and swap with the
current weapon.

Head Scaling

DPad style ui control.

Using touchpad to control the ui was pretty bad, this now requires you
to press it in like a DPAD.

Not sure if I want to make an additional change, I keep wanting to click
the middle as if that selects. Right now selecting is pressing in the
right touchpad.

Revert Left Touchpad Changes

My attempt at Adaptive Recentering was not working right, also removed
run since some unintentionally press it.
