More fixed camera modes

[thelusiv]

As I've been working on suspension and body roll and weight distribution I've realized it would be nice to have a few fixed camera modes looking directly at the front and back of the car, as well as ones looking at the left and right sides of the car. Also, it occurred to me that it might be nice to have a button that cycles through the camera modes for input devices with few buttons (gamepads, wheels, joysticks).
