Remove unused branches

I'm seeing a lot of branches but only 3 of them seems remotely active. Maybe consider cleaning them up?

Yep.
To be honest, I have no idea when I'll have some time to update this repo.
The main repo is now https://git.minetest.land/MineClone5/MineClone5
This is a backup copy, a bit outdated.
