Realistic Physics Mod

Minor update for the mod which includes separate files for 4x2 chassis, and for 6x2 and 6x4 chassis.
Please only use one version of the mod at one time.

Research partially based on this:

-Reduced damage coefficient slightly by around 17%
-Introduced separate download for 6x4 chassis
-Increased chassis suspension damping (for 6x4 chassis)
-Increased DAF XF's transmission differential ratio from 2.53 to 2.69
-Increased Renault Magnum's transmission differential ratio from 2.64 to 3.08
-Increased Scania R-series' transmission differential ratio from 2.59 to 3.08
-Increased Volvo FH16's transmission differential ratio from 2.64 to 3.40
