RPG Regen

I've re written the entire plugin and made sure it works on Minecraft 1.19.4. It should work with versions 1.17 to 1.20 as I'm not using version dependent classes in the code. As for older versions (prior to 1.17) I don't intend to test it. If there's a high enough demand I'll see what I can do to allow RPGRegen to work on old Minecraft versions.

Also, I changed the url of the source code to a new one containing the entirety of the code. I'll include a README.md file soon enough.

Regarding configurations most of the old options exist but with some minor changes (I'll add particle animations back later).

If you encounter issues prioritize the Github issue section by opening a ticket.

I hope the plugin will please old and new users!
