Changes

Units Unit '''license_plate_data''' has new attributes: '''background_front''', '''background_rear'''. Both are strings (up to 32 characters). Default , default values are "front" and "rear" respective. Texture with given name is looked for as ''material/ui/lp/<country>/*.mat'' file.Proper usage for variants of texture background is now per vehicle '''license_plate_type''' in '''traffic_vehicle''' classas was text of the plate. If no class type is defined first class is used as default the game tries to guess from vehicle '''speed_class''' (typically "like car" class, truck or bus). All other vehicle classes has to be defined explicitlyor they get some default (either car or first defined license plate type).

Due to interaction with player-owned vehicles system (apportioned trucks and trailer in US) such textures should still be named "truck_front", "truck_rear" or "trailer" respectively (like they were before). Failing to use these names in license plate definitions will end with improper license plate backgrounds for player vehicles.
