Changed how mob head drop limitations work (from spawners and eggs).
Added custom GUI slot numbers and icon lore flexibility. You can now split most lore lines with two consecutive semicolons (";;") to start a new lore line.
Fixed bug that caused the GUI total sale value to not update.
Added maximum value option for dropped heads. If the value of the dropped head is less than the amount specified, the head will be treated as though it's worth $0.00.
Added wanted boards.
Known Problems:
Wanted boards are currently a bit touchy. For a currently unknown reason, wanted boards will not survive a server restart. If your server restarts frequently, I recommend waiting until I can get this bug ironed out to add wanted boards to your server.
