[ansel] Patch for setting order on image upload

[Heath S. Hendrickson]

Attached is a small patch to lib/Gallery.php that does two things:

1) stores the current time() in the 'date-uploaded' attribute for future 
use (like a page of the last X images uploaded).  I did notice that a 
'date-created' attribute was being set in the Gallery.php code, but I 
haven't traced it through to know if that's reliable for uploaded time 
or if anything else might change that value... if it's reliable, then 
just remove this part of the patch (3 lines)

2) set's the datatree_order for an uploaded image to be the num-images 
for the gallery (placing it at the end of the gallery)
