Give ?uselessness that Xom chess piece functionality

[Leszczynek]

You know, that item that nobody used or cared for that was in trunk for a few weeks a few full releases ago and got removed. It would fit the theme of random uselessness pretty well. Read it while worshipping Xom and he does something random.

Too much of a groundbreaking idea to post in GDD, I think.
