XNAT-3185 Changed identifier to Referenced nomenclature, added ReferencingExtractor interface for extractors that need to be able to
reference the higher-level identifier object. Changed scripted session assignment extractor to pass full DICOM object to script instead
of just selected tags. Updated configurations accordingly.
XNAT-3383: Created new annotation to allow specification of restlet matching mode
XNAT-3382: INvalid SQL was breaking and clogging security.log
Fix for XNAT-3362 - used Running Title (secondary_id or secondary_ID?) Also, more user-friendly behavior for email fields on forgot login page (only selects input text instead of clearing it).
