Fix for crops transforming into "Mystery Plants" after their last growing stage. They still mostly returned their crops when harvested but it was breaking the Sugar Beets from "AnaLGiN's Renewable Food Resources"

Also added a compatibility patch for "Xnertot Farmable Trees" so that trees don't "turn old" if you don't harvest their fruit (since it's basically equivalent to rotting and you'd have to replant them)

Changed the way it works to make it even more resilient to mod incompatibilities.
