Detection for users of special Jabber-based service, aka Google Talk, Sky Messager, ... and show an iconset like we do for transported contact (msn, icq, ...)
I've got an idea about icons, as transported contacts are detected with the string "icq" "msn" or other, why do we not include a detection for the users of special Jabber service (based on a string in the "after @" part of the JID) aka Google Talk (string "talk.google"), Sky Messager (string "skymess"), ..., and show a specific iconset for each ? If it's ok, I can try to draw the iconsets we'll need
