Change-uid

Modifying constructor for uid structures.

Syntax

(change-uid x 
            [:uid <uid>])

This is an often useful alternative to make-uid.

We construct a new uid structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.
