LDEV-79: Added a new DISABLED state for a lesson - when disabled the lesson shouldn't be returned to users. Changed getLessonsForUser() to not return DISABLED lessons, but left getAllLessons() getting all (including disabled) lessons. But added a comment to indicate that getAllLessons includes disabled lessons.
