course: restore the field definition as a plain data type
Restored from e6873dd7^ with enforcebeanname=courseSearcher removed, so it resolves to the default dataSearcher. searchtype learningGroup -> pod on the image fields. No searcher class, no UI module - the course module is left for the revamp.
