Entity-specific Variables

There is a type of variable called Player Persistent, which is basically a variable that has a specific value for each player.

I think it would be really useful if we could have this for mobs. That way, mobs would be able to store some data, which would also be mush easier than using NBT tags, which don't work like 99% of the time!

That's another thing you guys should fix, which is that the "get entity NBT" and "set entity NBT" blocks almost never work! I would use the "/data get" command, but there is no way to get and/or use the value it spits out, so it's kinda useless.

Please consider adding the above features.
