Rally 7 - 1.0.6

Rally 7 is a car racing game from Infukor inspired by an arcade classic with a similar name. Written in Python and using Pygame and Numeric, it should be playable on a number of different platforms given a fast enough computer. The aim of the game is to navigate your car around the rally course - a maze surrounded by scenery - collecting flags and avoiding rocks and the red cars, making sure that the flags are cleared before your fuel runs out. If the red cars get too close, a smoke screen can be created to make them crash, but since this uses fuel, it may be best not to do so too often.

Added a "no audio" option and better audio device error handling.
