HEAD
Bug 4943. Can now include custom roles used in course to build list of course users from which group members are selected. Also form element names can now contain non-alpha characters without breaking SetFormElements() javascript by referring to elements as formName.elements['name'] etc. Need to rewrite any / in custom role as _ has been eliminated (so conversion no longer required for autosec records in coursegroup.db).
