1.6

Added Class 507! (Actually they looked almost the same)
Overhaul! (sort of.) Added some details on the front, used a new texture for the front (from 507001), replacing the ugly front texture from 508114. Also used a new seat texture to replace the old one.
Old interior version for both Classes 507 and 508.
Added compressor sounds for both Classes 507 and 508.
Nameplates! Instructions are provided on the texture file.
Added the handrails near the door that I forgot to add.
