[ansel] Patch to Gallery.php

[Heath S. Hendrickson]

I noticed a little flaw in the logic of the getDefaultImage() function 
in lib/Gallery.php.  It wasn't properly handling the case where 
['default'] = -1 and ['num-images'] = 0 (in cases where you had an empty 
gallery, it was displaying an error where the default image thumbnail 
was supposed to be, instead of displaying nothing).

Here's a patch to fix it.
