More Realistic v 20251122

Version 20251122:
* Add converted Mack Superliner (truck)
* Add converted New Holland LWB PLMI (tractor)
* Trailers attacher joint tweaking
* Auto gear shifting takes into account “virtual target speed” and “engine load” to allow upshifting at partial throttle => more than 70% throttle input means the operator want to shift up if possible. Less than 25% throttle input means the operator wants to downshift if possible
* New way of overriding DLC vehicles => we keep a “perfect copy” file of the DLC vehicle xml (faster to update it with a new version if needed)
* Add converted Holmer terraDos T5.40 sugarbeet harvester
* Fix bug with default MR CVT = sometimes (mostly in reverse), even when fully accelerating, we couldn’t reach the top reverse speed (engine rpm was still)
* Updated versatile/ford tractors from prairie DLC to take into account the modified i3d file from Giants
