This is a very minor contribution, but something that I find useful.
Basically it allows you to see the product model numbers in the admin
category/product listing, and also sorts by model number.
I work on a site that sells women?s clothing, and has many products
by different vendors that have very similar names.
The changes in this contribution just saves me time while looking for
a specific product to edit. This should work with most snapshots.
I have tested it with one from mid August 2002, November 2002, and January 16, 2003.
