&coursegroups() and &get_group_settings() moved to longroup.pm, which contains general utility functions for asking about groups. Also contains &group_changes() which is used to add/drop group memberships as a result of role changes, as determined by group settings for auto-add and auto-drop. 'none' and 'all' are now reserved words which may not be used as section or group names, so they can be used instead of _all and _none when specifying auto-add and auto-drop settings for all sections or no section roles.
