Update 12: Look and FPS options

- static deathcams now follow faces instead
- jumping more realistic (no "air walking")
- options to limit frames per second for
much better performance and consistency
- you can also adjust graphics quality in-game.
use home / end, page up / down, on keyboard.
- option to set controller sensitivities
- changed joystick identifier to an image

Check if this is ok. We want to start adding new map types and game modes!
