title: Unfriending someone through the Facebook API?
body: <p>Is it possible to remove a friend relationship between two FB users through the API? I'm thinking that it's not, but (if not) is it possible to at least bring up a dialog that would let the user request the unfriending, similar to how the Friends Dialog (http://developers.facebook.com/docs/reference/dialogs/friends/) lets a user send a friend invitation?</p>
