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 was because relationship_type_id was being used in the query.Mapping for this import should work fine for all now and export should show all mappings except for a case when someone maps a process through the object page.  The relationship that is being created for this process does not follow the same guidelines as that of an OrgGroup/System and more work on that will be another story.
