Collaboration in Didit: assigning, watching, and completing together

The typical Didit flow works like this: Someone creates a Didit for someone else, potentially includes a watcher so they can see the request, then the assignee and requester discuss the Didit using the discussion feature. The watcher gets the benefit of following along on that discussion if they'd like. When it's done, the assignee completes it and the requester gets notified automatically. The watcher is notified as well. If it goes overdue, everyone gets notified about that too.
