windows build + cars

[zimluura]

ok, it's done. everything is converted to v2. and the driver positions are mostly good. some smaller cars will not work until there's some kind of driver scale option. but evenso the driver doesn't look horrible.

the c7 has an opaque windscreen, but the hood-view will still work.

the m8 and the xm aren't converted. i have done the files for them. but since i can't test them (or figure out their driver positions) i haven't committed them.

i can write a torque curve for the xm and get that working if you want.
same goes with the m8 if you can tell me what it needs to make it load.

fuel tanks might be on the wrong L/R side, or they might be correct, really just something i can't be sure of.

all contact point sections have been removed (added as particles for points over 1kg)
