Keyboard Steering v1.2.1.0

This is mod is designed to give a more analog-like control to the steering and accleration inputs when using a keyboard.

Changelog:
v1.1.0.0:
- Added key binding detection for steering input keys
- Doubled the "Steering Back Speed" setting range (now 0-200%)
- Added a key to disable the mod (unbound by default)
v1.2.0.0:
- Added smoothing of the accelerator input (single player only)
- Fixed some multiplayer bugs
v1.2.1.0:
- Fixed a problem with the steering wheel position averaging in some vehicles

Key Features:
- Steering input increases linearly for first 500ms of steering input
- Steering input drops off linearly at the same rate when there are no key presses
- Steer back force is proportional to road speed (so you can still manouver normally at low speeds)
- There is a limit to the steering angle that is also proportional to road speed
- Press both left and right keys at the same time you will go straight (instead of turning right as you do in standard game)
- There is no steering back force when stationary, even at 100% for the steering back setting
- Acceleration input is smoothed to reduce the twitching of a vehicle when tapping the accelerator key (single player only)

IMPORTANT:
- If you are using a game pad or controller then the mod will do nothing
- The "Steering Sensitivity" setting in the game is unchanged
- The "Steering Back Speed" setting now controls the amount of reset force and also the range for the maximum steering angle
