- SW: Uplift DoPlayerHorizon() with changes to serve as basis for standardised backend player horizon function.

Browse source 
* Pre-requisite to make it possible to stop using Q16.16 for horizon input.
* Perform look up/down and aim up/down using true pitch without the need for a helper.
* Adapt SW's return to center function to work based on true pitch (Duke's is a bit too fast for my liking).
* Duke's aim up/down and look up/down is 6 & 12 respectively, SW's is 8 & 16 respectively. Let's go half-way at 7 & 14.
