register users automatically in groups
When creating new course groups with new parent + tick 'Schrijf cursusleden willekeurig in':
action is completed in Desiderius 4.0 (without registering users, but at least the docs and fora and groups are made.
action is not completed in TestEVH: progress icon keeps running. I aborted the action after 15 minutes. (!!only very few users in this course - Testcursus steven)
