Make minor notification state persistent

This occurs due to fact that the minor notification status is not persistent, i.e. it is not stored in the DB. It is only known during the session, and thus only able to distinguish between sending 'Space' or 'Page' notification (affecting the Watching functionality only)

else if ( ( (PageUpdateEvent) event).isMinorEdit() )

{ shouldNotify = false; }

else

{ PageUpdateEvent pageUpdateEvent = (PageUpdateEvent)event; notificationData.addToContext("originalContent", pageUpdateEvent.getOriginalPage()); notificationData.setTemplateName("editpage-notification.vm"); }

if (shouldNotify)

{ sendSpaceNotifications(space, notificationData); sendPageNotifications(page, notificationData); }
