[ansel] Ansel Watermark patch

[Heath S. Hendrickson]

Here's a simple patch to change the watermark from "Watermarked by AUTH" 
to something more appropriate "(c) YEAR AUTH".

I'd like it to be the users full name and not the login name, but I 
didn't have a chance to dig around to find out if that's something I can 
access or not.

It would be nicest of all to have the watermark configurable via an 
option, but that's way beyond my PHP skills at this point (consider it a 
feature request).
