Added multi-arena and better multi-world support! (use '/cc create <arena name>' to create an arena in a world)
Fixed wrong command descriptions in-game.
Added economy support for rewards (Vault)!
Added optional auto-start when doing /cc join (set autostart to 'true' for this in the config.yml)!
Important changes
Because I have added multi world support, the saving of locations has been changed. It is very important that you set all your locations again (one more time). Please delete your current 'locations.yml' and re-set all the points manually. Sorry for the trouble, but it's required!
Also, add the new configuration options to your current config.yml (or delete your config.yml and simply run the plugin).
