Invitation: detail view shows accept/decline on expired invitations

[agjohnson]

I don't necessarily think this pattern is wrong, as the accept button is disabled in this case. However, Decline is maybe the wrong button to leave active here. Ideally, these buttons should be a single Dismiss button, but this might require either reusing the decline form button or adding a parameter for dismiss to the invite handler view.
