Kamaz 5320 & Nefaz 8560 Autoload pack

This is a conversion of FS17 truck Kamaz 5320 and trailer Nefaz 8560 that matches it.
Credits to FS17 modders: DANG, W_R
V1.2 specifications:
- Cab suspension is added
- Seat suspension is added
- Removed "mission pallets" from autoload menu. This had to be made because I didn't found script that could support both mission pallets feature and two vehicles at the same time (truck with trailer attached)
