[development] Themes and modules have a new method for adding screenshots

re: http://drupal.org/node/202856

You can now add screenshots to your modules and themes via image assist. 
There's a new fieldset, "attached images" with a spot to upload. A thumbnail 
is automatically created and placed on the project node. This takes the 
place of the old links on themes so please remove those.

Everyone who has used their CVS account in the last year has been given the 
role with access to it. If you have any problems, please file an issue.
