Comment 5 for bug 494967

As the suggestion from Parin Porecha, Bugzilla plugin has been just converted to a synchronization backend service. It works, now. However, there is still other related enhancement to be done. For example, provide configuration dialog to allow user to define the prefered Bugzilla services when the backend management dialog refactor is done. And another possible enhancement is to make CustomeInfoBar be friend to multiple messages from each enabled backend in threading environment, that will be described in another bug.
