I did a little PBR Update; added real PBR point; added PBR glass and added better thumbnails.

Good stuf:
ok so these mod is outodated I did these:
Fixed missing engine sound folder; added PBR paint and PBR black material; fixed missing material on the brakes; fixed missing engine mesh; added four new config and added the info for it also I removed some unless parts and Jbeams and I fixed the missing tires; and I added new thumbnails.
Bad stuf: Jbeams are weird and not the best.
