[Feature] Separate FPS Egg Aiming Control vs Camera Control (when free camera/inverted look is enabled)

Ran into a small thing, I wanted to test out the tooie FPS egg aiming enhancement but I already had the camera enhancements for X-axis with free look and inverted setting.

This looks like it affected the way you aim, which I do not aim inverted in FPS games. Just wanted to add this as an odd behavior artifact from free look camera controls.

Start by reproducing the interaction between the Tooie FPS egg aiming enhancement and the free camera's X-axis and inverted-look settings. Trace the existing aiming and camera-control entry points, then verify that FPS egg aiming and camera control respond independently without changing the requested behavior.
