Added a DropPartyCommand interface. All commands must implement this interface to be able to be used in the CommandController.

Made the CommandController modular, all commands are added in a map.

Fixed CommandListChests. Using the variables instead of the toString() (Kinda foolish to do it :P)

Removed a useless variable in DropParty
Merge pull request #2 from greatman/master
