Be able to add notifications types from a wiki page

I've checked the blog app and making it register a notification when a blog post is published is extremely complex:

• BlogPostPublishedEvent: new event
• BlogPostPublishedEventDescriptor: descriptor for the event
• templates/notification.vm
• ApplicationResources.properties
• BlogNotificationDisplayer: render the notification
• Translations.xml
• BlogDocumentSavedListener: listener
• BlogPostPublishedEventDescriptorTest: test class
• BlogDocumentSavedListenerTest: test class
• BlogNotificationDisplayerTest: test class

What we need is to wrap this in a much simpler system so that an Application could simply add an XObject to a page and that should be it.
