Initial fixes

[PapiOphidian]

This PR is a draft for now because it removes some mod compatibility mixins and doesn't 100% work all the time.

I believe the only issues remaining is that the FallingBlockEntity gives some issues and can cause a crash.

Chests also automatically close after a seemingly random amount of time. It's possible it's just double chests. I tested some other inventories like single chests and barrels and no issues seemingly.

I do need your help on this since I am only a beginner on mc modding and a lot of my stuff could be wrong or done better. I've just mostly done blanket fixes.

It looks like chests automatically closing is coming from this line:

if (!this.world.isClient && this.currentScreenHandler != null && !this.currentScreenHandler.canUse(this)) {
	this.closeHandledScreen();
	this.currentScreenHandler = this.playerScreenHandler;
}

Although it perplexes me since this should not be run in the case of chests unless the screen handler is being updated with one that can't be used.
