    telepathyClient: Add alias change notifiers
    
    Update the Source title when an contact's alias changes, and
    also also add a minor meta message like the current timestamps.
    
    Updating the alias of a 'presenced' contact will overwrite the
    current title, and it will also not update the summary item title
    right now due to limitations of the message tray.
