Added diffrent varrients

1. I moved the second axle a bit to the rear and also strenthend the susspention to get it not to hit the body.
2. Reworked steering angles, on the 1st and 4th axle and added 3rd axle turning. I also took out steering castor.
3. Fixed the top heavy issue please report if it is leaning to far forward or still a bit to far back, the cabin wasn't resting in the front, but in the center.
4. Moved the tractor more back to fix the semi's issues. Please report if I need to move it more.
5. Added Kamaz Highway Offroad, and I didn't remove the Kraz offroad simply because I like them.
