Car graphics config

But I've got the impression it would be too complex for the user. Thus, I've decided to switch back to predefined components.

i think this will be ok for the average car creator. so long as the wiki documents which parts are required.

i like having a shared data folder, but most cars would want 100% custom meshes for that car, and it give's the car some semblance of being self contained. at least in what they don't use from the carparts directory.

with it this way will be nicer if the number of cars increases allot. because making the limited install with only 4 cars available, won't be tons of work.
