HEAD
Enforcing privileges for actions on course group portfolio files. Tabular display of access controls provided for group members with access to group repository, but without privilege needed to add/delete/update access controls for group files. Some text improvements, and case fixes for triggering correct roles nomenclature when dependent on Course/Group context.
