Rekey changes the keyword of an item.
It differs from rename in that it is not the name that is seen, but the
name the object is identified as and can be looked at or picked up as.
For example, if a sword of legend was rekeyed to blade , get sword would
no longer work with this item. (get blade would pick up the item)
When an item is rekeyed, one of the words from the short description
MUST be used in the rekey.
Rekey is included in the rename fee. See help glory for more information.
