HEAD
Include institutional course code in nohist_courseids.db.
Format of entries in nohist_courseids.db now -
course_id = description:institutional code:last activity
both (keys and values are escaped).
lonnet::courseiddump now returns escaped values in hash (keys are unescaped),
to preserve the : separator between description and institutional code.
