Changeset 8445 for code/branches/tutoriallevel2/src/modules/notifications/NotificationManager.cc

Message:

NotificationListener is new an entity which is informed of new notifications. The NotificationManager is, so far, the only NotificationListener. This means that Notifications can now be sent from within orxonox (though not libraries or external).
Also introduced notification commands to affect the NotificationQueues in more ways than just have them display messages (e.g. clearing them).
Added a message type which allows to send Notifications of different importance, allowing the NotificationQueus to display them differently.
