Add mobile controls and optimized settings to Truck Town

On mobile platforms, the vehicle automatically accelerates. Touch the left and right edges of the screen to steer. Touch the middle of the screen to brake/reverse (this also temporarily stops acceleration). - Fix braking not working correctly (and make breaking stronger to make vehicles easier to control at high speeds). - Allow using the D-Pad for steering and X/Square for braking. - Tweak exhaust particles to be more subtle and fade more smoothly. - Change spawn position to a location that's more straightforward to drive.
