Added security to the monitoring calls - the calls to update a lesson now check that the user either the owner of the lesson or a staff member for the lesson.
Renamed the disabled state to "removed". This will make it less confusing with the u/i which describes the suspended as disabled. Cleaned up MonitoringAction so that it doesn't try to forward to a jsp.
Changed learning design activities and transition collections to use all-delete-orphan cascade management. This will ensure that the secondary records are created and removed as required.This required fixing code that trigger cascade problems and also highlighted some session problems with the learner cache created by Jacky.
