Added arena system!

An arena system has been added that allows you to make arenas with:

• Block Break/Place permissions
• Block decay time
• Explosion Damage/Block breaking
• Map regeneration time

When creating the arena, you need to select 2 points with a wand you get from the /selection-wand command. Then, you can type the /add-arena <name> command, that opens the menu you can view in the first picture.
When you are done configuring the arena, you can click the Confirm button which saves the map as a schematic and creates the arena.

If you want to edit the map, or you simply just want to regenerate it, you can enter the /arenas <name> command, which brings up the menu seen in the third image, or you can just simply type /arenas to open the menu seen in the second image, where you can browse the arenas.

When editing an arena, currently you can only reset it, delete it and rename it. In a future update, I’ll add the other settings too.

If you are wondering, yes this was written by me. I just use a frick ton of markdown, and like to format my messages. AI wasn’t used in this message at all.
