Title: Tool to remove ghosted custom blocks

On rare occasions a customblock will fail to be removed from the world. This means all future blocks at that location will be displayed in Spoutcraft as the custom block texture. This tool removes the override when you use "/spout ghostblock" and then hit the block in question.
