Refactored data serializing for projector websocket connection. * Refactor the way that the projector autoupdate get its data. * Fixed missing assignment slide title for hidden items. * Release all items for item list slide and list of speakers slide. Fixed error with motion workflow. * Created CollectionElement class which helps to handle autoupdate.
