[ENHANCEMENT] Implement animation priority

True... or False... call it.

Description

Characters had a very weird implementation of animation priority. Singing was set to have the highest priority, despite not even being set to ignore other animations, overriding any other animation that may play instead. It was a mess.
This PR introduces a json-configurable animation priority system, which should hopefully make the animations a lot more consistent. The new system supports adding asterisks to animations, in case multiple animations should have the same priority. Any animation that isn't in the configurable array assumes the index of -1 and therefore has the highest priority. The default animation priority queue is ["sing*", "idle"] or ["sing*", "dance*"], meaning that sing and miss animations should happen before the idling animation(s).

Caution

This is a breaking change for mods using ignoreExclusionPref, as well as for the base game scripts using it! I've opened a PR in the assets repo (FunkinCrew/funkin.assets#295) that should be merged as well so that there's no script errors being thrown on the screen for every character initialization.

This implementation is kind of odd, and doesn't work with other types of sprites.

I was imagining that the playAnimation function, instead of having a force argument, would have a numeric priority with a default value, with that value determining whether one animation can override another.
