Auto retry when user comes online again

There are some users that use the same account on different computers where they don't have the same files shared. Or they have the files on an external disk that is not always connected. The result is that queued files sometimes fail with "File not shared". But the same user later may have the files again if he uses the other computer or has the external disk connected. But the failed queues stay failed unless I manually try them again. In this case I'd like soulseek to retry by itself every time the user comes online again. It already knows this event as the user icon changes.
