This changes the farming API such that any nodedef with paramtype2 and place_param2 are passed through to all the plant stages of the farming plant. This allows plants to use an alternative mesh for the plantlike drawtype, and provide a bit of graphical variation in plants. We enable this for wheat, using place_param2 = 3, which is the '#' shaped plant mesh. If you would actually be able to give yourself this plant in creative or through /give, you would also get the same '#' shape.
