Subject: Added the concept of "permanent" messages that we show to admins. 
 Use this to show a "your thumbs/resizes are out of date" message whenever we
 change the graphics rules.  Tweak watermark module to add graphics rules
 whenever we make a change, which triggers the graphics module to add the
 permanent message.
