plantlife_modpack/plants_lib/init.lua
Vanessa Ezekowitz 94e21c0cf6 multiple changes
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.
