System/Proc export fixes. No data error fix and other clean up.

System and Process export was not showing the OrgGroup, System,Process mappings that a specific sys/proc object had.  This wasbecause relationship_type_id was being used in the query.Mapping for this import should work fine for all now and exportshould show all mappings except for a case when someone mapsa process through the object page.  The relationship thatis being created for this process does not follow the sameguidelines as that of an OrgGroup/System and more workon that will be another story.
