Allow adding contacts from bonjour/link-local/zeroconf contact details

Description
For instance, if I see some friends via the "People Nearby" list, it would be nice if I could just add them as a contact. In the implementation, I guess this would, for instance, discover if they have a jabber account (empathy clients could tell other empathy clients this) and then add it as a contact to my jabber account.
