New Car Plus Bugfix

Mixed in the first new car. It's designed for 1080p rather than 720p so may look better fullscreen than the old car does.

Also, and the real reason I hurried to upload this, I fixed a sound bug that would cause repeated "fail" sounds to play simultaneously (making a grating glitchy sound) if you used a gamepad axis (e.g. trigger) to fire attacks. I hate it when bugs get uploaded.
