author: AnduinLothar    <Anduin@cosmosui.org>

Remember friends level, class and location after they've logged off. Thanks to George Warner for this original hack.
TODO: check how old the data is and not display it if older than some arbitrary value

-Rerelease in addon form.
-Modified Width for offline overflow with long location names.
v1.1 (4/29/05)
