Lamborghini Countach fix and update v2.0

Good stuff:
ok, so this mod is outdated, i did this:
Fixed missing engine sound folder; added material PBR paint and PBR black; fixed missing material on brakes; fixed missing engine mesh; added four new configurations and added information for them, also I removed some parts of the engine and Jbeams and fixed missing tires; and I added new thumbnails.
