Need to be able to copy/paste worlds into different categories.

Me and my sister like to play block fortress together, and I decided to make a maze map. I didnt realize that I had made the world in sand-box mode,and after working all day to create the maze I found out that to play the world on arena mode I should have made it in the "Arena" tab. Thanks for reading! Great job making the game!
