Outdated Otnas CityCruiser 1.5 W4 - Now w/ Quadvector! 1.2

Update 1.2:
- The CityCruiser W4 now has torque vectoring called as 'QuadVector'. It is based on @gtpdzbiz 's Pessima active differentials with a little bit modifications. By pressing F, you could change drive modes from Tarmac, Dirt, Snow, and Drift. Torque vectoring allows to have various power splits in every wheel.

Thank you :
@gtpdzbiz for letting me use on the active differential mod.
@Inn0centJok3r for helping me put the code to work.
