FS19 JD 6M AdBlue Added v1.0.0.0

This is a fix to add AdBlue usage to the John Deere 6M Series. After the AdBlue mod was released I noticed a good number of the vehicles in 19 wasn’t scripted to even use it. So I set about to fix this and thought I would share these fixes with those that would like them and not want to have to do it themselves.
