SwitchyFiguraAPI listening functions are permanent

[Aproxia-dev]

When you load an avatar that uses the SwitchyFiguraAPI, and then reload it or load a different one, the listening functions from the first loaded avatar don't get removed.

This leads to the functions being ran multiple times after a switch, or the functions get ran while the avatar that uses the API isn't loaded anymore.

Yeah, the previous LUA environment doesn't seem to get "discarded" on Switchy's side when an avatar reload occurs.

speaking of the SwitchyFiguraAPI, there's a small mistake in the documentation, where on this line, the oldPreset and newPreset are swapped.

So this is theoretically fixed in 2.6.4 so please give it a try! I have no way of testing myself.
