car components, damage, a new windows build

[zimluura]

i think adapting the .car file so you can have it load several different .joe models would be really good because modelers could start building cars out of sub-parts right now.

then later on the code could be added to provide:
* doors and hoods that open up (and get replaced with carbon fiber, then get ripped off in a crash)

* mirrors that fold (and then get removed for less drag, or possibly crack and break off if they weren't removed and you grind the wall)

* antennas that extend (or nixed during weight reduction)

* engine swaps that have a visual difference when you look under the hood (and look different when they're on fire)

but all that stuff will take lots of time to code and is probably far down the road. loading an arbitrary amount of .joe files for driving around the track is the first step and shouldn't be bad to code.
