Title: Added a delete_tag method to Tagger

This is different from untag (which calls remove) because in that
case the tag still exists and is tied to the Tagger, but no longer
to the Taggable. Using delete_tag will remove the tag from both
the Taggable and the Tagger by deleting it permanently from the
database.
