This commit adds any nodes which make use of a grass palette to a `grass_palette` group, to avoid having to create a list of said nodes every time. I also added one line of code to potted ferns, in preparation for when I get to adding biome coloured potted ferns, which currently use a fixed colour instead of the biome's colour.
