CSPACE-2818, CSPACE-3537 Refactored logic that handles authorityRefs, refObjs, and displayName update, so that it can handle authRefs in deeply nested structures. Still awaiting latest code from Nuxeo to integrate their updated search, but this change at least fixes 2818, and makes us ready for the fix for 3537 and 2323. Also cleaned up handling of authorityRefs for garbage values - now produces a log error and does not produce an authorityRef item (was producing an empty one). Also added a partial fix and notes to remove the hard-coded resource paths for authority types.
