Patches for gallery image reordering

"Heath S. Hendrickson" <[email protected]>
Newsgroups gmane.comp.horde.ansel
Message-ID <[email protected]> 
Attached are patches and new files to add gallery reording to Ansel.

New Files:
    reorder.php
    templates/view/reorderHeader.inc

Modified File:
    templates/view/gallery.inc

I implemented the gallery display ordering via the gallery.inc file.  It 
would have been major surgery to change the DataTree driver, and this 
works well enough.  It's easy to remove once the DataTree driver has 
been updated and tested.

I also made it so that if an explicit order wasn't set for a gallery, 
that it still functions as it has, meaning that there is no update to 
the database necessary...

Thanks,
h
