SwapThings

Fixed the inventorySlotReplacer command so that Slot num = -1 will do random, =0 will always target held item, >0 will do the first slot number starting with 1 (and if the number given is more than the player's inventory size it will minus the inventory size until it fits. I.e. 42 or 83 will do - 41 and do the 1st slot)

Added config option to turn off all messages put into chat when a command is run (except for the displaydeathboard command).
