This patch addresses an issue where AI racers could buy themselves locked cars if they had enough cash, adjusts balance a little more and makes the game more resilient to rare situations, i.e. dealing with corrupt or missing track files.

The reason for input binding change is that when people used Alt+Tab to get out of the game, Left Alt was triggering the camera rotation change, so it was a bad key mapping. I chose to not force reset existing mappings, so if you want to quickly jump to defaults, go to "Settings" > "Input" and click "Restore Defaults" on top.
