Make bushes use default farming mod's flour for making pies instead of jungle grass, if that mod is installed. Junglegrass will be used if farming is not present. Make bushes mod support farming_plus more completely - either its or bushes' strawberries may be used to make a strawberry pie or a mixed fruit pie - mix and match the two types of strawberries as desired. move clone node function from junglegrass mod to plants_lib so that other mods can use it.
