The Tree Update: Makes it easier for Dionae to color their body markings, removes hairstyles and skin tone from them, makes the tail marking into an actual tail

Basically, uses the species' list of skin color presets, if any, to add a button for body markings to select the same presets. This is only really useful for Dionae at the moment, or at least I imagine so. Skin tones and hairstyles were also removed from Dionae, as figuring out how to add selectable tone for body markings was too much of a hassle and adding presets for hairstyles as well seemed redundant. I was thinking of adding a "random body markings" proc to resolve the issue of newly formed gestalts not spawning with any hair, but let me know if this is desired.

I discussed this with the Diona lore maintainer beforehand, but the team is free to change their mind or request more features at any time.
