showSuppressedNotifications

Whether previously suppressed notifications (indicated by numberOfSuppressedNotifications) should be presented to the user. When true, newly incoming notifications that would otherwise be suppressed should be presented as well.

This property may be changed using setShowSuppressedNotifications. Though the notification center is typically the only client that sets or reads this property, exposing this boolean explicitly allows the notification center to present its UI consistently with the state in the service.
