    appNotification: Add class CloseNotification
    
    We are about to land IRC URL parsing which error
    handling requires using an app notification when
    IRC URLs cannot be properly parsed. This adds a
    new CloseNotification class which shows a notification
    for 7 seconds along with a close button.
