Marking this as triaged although it encapsulates several bugs (one for adding infrastructure to BugWatch for tracking patches, one for adding infrastructure to ExternalBugTracker, one for updating BugWatchImporter and one each for adding the requisite code to each ExternalBugTracker subclass). Once we come to look at implementing this we can file those bugs separately.
