Better Animations

This update includes a complete restructure of all the code for the player model for faster resourcepack loading, more responsive animations when switching between states, less glitches during variable calculation, elimination of redundant code

Things that don't work right now:
Swimming animation (up and down)
Falling animation

Things yet to be reworked:
Elyta, capes

Please report any issues you find as soon as possible as version 46 and its subsequent versions is attempting to fix all bugs

Note: Better Expressions will only be updated with the final v46 release once the rework is done. As no new features are being added, it should still be usable (exclusing a maintenance update when the next minecraft version releases)

Thank you all :)
