4017 * Basically those items, used with a marked item, transform both items into something
4018 * else.
4019 * "Transformer" item has food decreased by 1, removed if 0 (0 at start means illimited)..
4020 * Change information is contained in the 'slaying' field of the marked item.
4021 * The format is as follow: transformer:[number ]yield[;transformer:...].
4022 * This way an item can be transformed in many things, and/or many objects.
4023 * The 'slaying' field for transformer is used as verb for the action.
