Number of days a topic subscription lasts

[klumy]

"Number of days a topic subscription lasts" setting for topic notification would be great.

This is useful to automatically unsubscribe from a subscription after the number of days entered have passed.

That does sound useful esspecially since once a topic dies it theres no reason to be subscribed and that takes up space on the server. (not much but its dumb to have it there)
