Creating a grouping failing when max number of groups null - now allows 99 of groups. Also changed the calculation of urls so that " null + some parameter" = null rather than null?param=blah
Random grouping now working - changed to make learner service changes to stop a hibernate lazy initialisation exception when grouping has just been run.
Replaced getAllLessonsWDDX, getLessonData with getLessonDetails. Suits the change from listing all the lessons in the monitoring client to just working with a single lesson.
