Added GC Steering Wheel emulation.

To set it up, change the Port 1 controller to "Steering Wheel" under the GameCube tab. This will tell the game that you have a force feedback steering wheel connected. In the Gamecube Pad Settings, change the Rumble Motor to "Constant". Configure the controls: Main Stick Left/Right = Steer Left/Right Main Stick Up = Accelerate Main Stick Down = Brake Thanks to ulao for the device communications info.
