v0.20.2-api5: New Handler!

Depends on FoxCore v0.20.1-api5

Inscrutable kept bugging me about the old permission handler. So I sat down and rewrote the whole thing.
So you have a new handler now. I'm too tired to explain how it works, but i took the liberty of adding tab completion and click actions, as usual, so you might be able to figure it out.

There's also bug fixes, as usual. I normally wouldn't make a new release so fast, but I made a major fix on FoxCore to make the client actually usable, but i also changed some things, so I needed to make a new release here too.

So have a new release just only a tad bit better than the previous one.

Have fun!
