Subject: The start of the notification module.  At this point, the icon has
 been added to the item menu in the sidebar (both photo and album).  There is
 a corresponding icon in themes/default/images that needs to be spruced up.
 You can add and remove notifications to albums and photos, but nothing
 happens under the covers for event handling.
