Fixed display of the parallel activities on the dummy monitoring screen. Previously it was using the activities from in the learning design and the parallel activity was a CGLIB entry, which didn't give access to the activities method. Added a new session parameter, activities, which contains a set of AuthoringActivityDTO objects and these are used in the place of the learning design.
The rule to work out whether to pre-initialise the tool session was wrong. Was initialising for grouped activities, we want to initialise the non-grouped activities.
