#13940 Introduced administrative notifications

* Notifications are no longer automatically sent to all administrators, only to subscribed ones
* New administrators are automatically subscribed, and when they are revoked, the subscriptions are deleted
* An update script must be run to subscribe all administrators to the new notification
* "Subscr. to notif" portlet appears if notifications are enabled or the user is admin
* Improvements to the javascript for content type subscription
