OPCraft w/ MUD v2

This is a port of OPCraft to MUD V2.

Port Notes

Not everything is ported over, in particular:

• plugins
• staking / claiming land
• crafting, recipes
• creative mode
• The component browser (the sidebar that appears when you press ~. This wasn't ported since MUD2 has a much nicer "component browser")

There is a patch to MUD because of a bug, which can be removed once this PR is merged in.

Running locally

1. Run pnpm install to install dependencies
2. Run pnpm run dev in the top directory
