Almost done with event regrowth.
Have to think about how to monitor player planted entities such as grass from tufts since the source code only pushes the onremove event for renewable resources. TODO: - implmenet event regrowth load/save - implement event regrowth CACHE/FAIL/SUCCESS states - currently the mod rehooks all entities every 3 seconds to mitigate the issue above but it eats performance. Maybe do it once per day? or simply don't care? - refactor natural regrowth's array iteration.
