LDEV-1261: Fixing a lazy loading exception that started when we removed the hibernate session filter on the user role import. The organisation can't be passed in from the web layer as it isn't connected to the session, and so when it tries to get the user organisation from the organisation, it throws a lazy loading exception.
Branching: Tweaking the branch objects so that the contribution flags are right for teacher chosen activities (and hence the button will appear to do the selection in monitoring) and some changes to make the teacher chosen screen logic easier.
Branching: Added a new field firstActivity to the SequenceActivity, so Flash can easily indicate where to start in a sequence activity. That way, the logic works in the same way as it does in a learning design.

Clarifying comparison for group - will now work even if the groups have the same order id. Removed unneeded saving logic from the import code now that the comparison is fixed.
LDEV-1261 improve import user speed by running in separate thread (bypass hibernate filter), and update browser with progress every 5 seconds so it doesn't timeout.
