SW: Make vehicle input better.

Browse source 
- Define new boolean 'on_vehicle' in PLAYERp struct for use with interpolating while on vehicle and other checks.
- Move horizon code back into separate DoPlayerHorizon() function. Adjusting horizon while in vehicle must come at the end of the DoPlayerOperate*() function.
- Make DoPlayerHorizon() accessible in game.cpp.
- Change code in DoPlayerHorizon() to process according how 'pp->on_vehicle' is set.
- Make scaleAdjustmentToInterval available outside of getinput().
- Don't process input at frame-rate while on a vehicle. Vehicle code is too difficult to process outside of the game's clock.

Partially based on NY00123's upstream implementation of tying player input to frame-rate.
