Kingston Belvedere Hirschfeld Edition 1.0

For all those who find the Kingston Belvedere horse trailer in uniform white too boring, I have added the following for customization:

- Color choice for the pendant
- Color choice for the rims
- Choice of different colored decals (the stripes)
- configurable Hirschfeld logos (different variants of Hirschfeld Logistics and Hirschfeld Hauling)
