[gnome-shell/wip/fmuellner/notification-redux: 24/93] calendar: Copy Source from MessageTray



commit ab37fd274eaa5b3184659c4f5ed91b2230e2b55b

    calendar: Copy Source from MessageTray
    
    The new notification system will still use the concept of notification
    sources, but heavily deemphasized and not as the primary entry point
    of the notification system. Therefore it is much easier to put the new
    system in place and move over once it's done than to modify the existing
    code gradually without breaking consumers.
