Replaced getAllLessonsWDDX, getLessonData with getLessonDetails. Suits the change from listing all the lessons in the monitoring client to just working with a single lesson.
Temporary indexContent page that points to Flash movies, set up for individual courses/classes rather than the old old organisation model. Done to allow Flash work to be done, while the admin work is in progress.
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.
Added "real" monitor page, which will contain the Flash movie. Doesn't replace the dummy pages yet as the required functionality doesn't exist yet. Once completed, the dummy pages will be removed.
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.
