[EXPERIMENTAL]Pointy Ear Slider

This is mostly a proof of concept. Adds a new slider that allows you to stretch the ears into various pointy shapes. I plan on tweaking and refining the shapes much more, but I'm uploading for now if you'd like to try it out as-is.

This messes up glasses sometimes. I plan on looking into that as well. Currently this is VERY unpolished. Why am I releasing this in such a raw, unpolished state? Because I'm not sure how quickly I'll be able to get this out, since I'm busy, and I'd like to let people have the option even if it isn't looking the best.

Shout out to Tarruvi for sharing their tips on importing deformers.
