Update albumuniversal.xml

Hi,
I've been trying to get information for my albums and most work fine using MusicBrainz.
However, in some particular cases where all the releases have the "Packaging" field populated, those releases are ignored since it's missing in the RegExp that checks the returned release. For instance, test the following albums:

http://musicbrainz.org/release-group/9e693829-7576-4360-9717-ba5d99242f61
http://musicbrainz.org/release-group/5048cda8-4269-3226-a289-71ef84c3ff0e
http://musicbrainz.org/release-group/03a27296-d762-3b20-8b2b-cfca9dfa9bdf

I tested the optional packaging xml tag in the RegExps and then the scraper started getting those releases correctly.
