Changed the permission of /tw addwall to thewalls.addregion
Changed the permission of /tw removewall to thewalls.removeregion
Added the commands /tw addbuildingregion and /tw removebuildingregion which are required in creating an arena and they are used to define the areas where players can place and break blocks!
Fixed a bug in the /tw setteamspawn command
Added a free setup that works with this version and upwards
