bringBadgeToFront

Sorts a comma-separated list of badges so that a given badge is listed first.

Note: It does not sort the badges alphabetically, and as such multiple calls may result in the order not ending up quite as imagined. Perform the procedure in reverse if possible, to guarantee the last badge is the first.
