Car and track manager

[thelusiv]

I'd like to see a "Manage Cars" button in the VDrift menu, where users could download new cars or delete unwanted cars. It wouldn't be too hard to set up a php script or something on this site that would serve a list of the names of cars available, and the game could basically use this list to determine the name of the file to download from sourceforge. We could also have another script that the game can hit to get car info to show a user before downloading, perhaps an image of the car, and a short description.

It would also be nice if this function would allow users to a) all the cars, b) some combination of individual cars, or c) a whole pack of cars, such as a rally pack, a drift pack, an autocross pack, etc... The installer should also be aware which ones are already downloaded and their modification date (to see if there are updates).
