New xenobotany gene - falling fruit

Created by: Killette2

What I want is pretty simple. Like how apples fall from a tree, plants with this gene will harvest themselves falling on the tile of the plant if not harvested after a certain amount of time. I would also allow this to be applicable to vines, allowing vines to be self harvesting like they used to before more recent changes from botany2 to botany3.

Whether this becomes a new gene, or gets mixed in with another group as some groups are mixed, is up in the air for discussion. Let's see what we should do with this idea.
