epic: improve SimpleFarming integration

[pollend]

SimpleFarming is a module that aims to provide a, well, simple farming implementation.
It tries to distance itself from complete realism and rather to give a basic and somewhat more abstract version of farming. It provides a few seeds which grow into full bushes, vines or trees. These can then be harvested for their produce, or destroyed for their seeds.

Content is housed in the EdibleFlora module, with "expansion packs" in the AdditionalVegetables and AdditionalFruits modules

In order to be fully active in JS, it needs to have the produce integrated with other modules, namely cooking and alchemy, as well as potentially expanded to be used in some non-food based plants (though this is optional)
