[ansel] Image watermark user pref patch

[Heath S. Hendrickson]

Attached is a patch that let's a user configure a custom watermark in 
there preferences.

It doesn't include the pop-up for defining the text on the fly, but it 
at least lets the user define the text in the preferences.

Ratches applied to config/prefs.php.dist and image.php
