Renamed /related_objects/ to /find_related_objects_has_resource/ and created two new services following the same pattern (find_related_objects_has_attachment and find_related_objects_has_role).  These services pull back resources where hasAttachment and hasRole are satisfied.
This was done so that the Attachments and Roles filters could be applied in the face page's Long List.  Since I had to stick w/ 3 seperate web service calls, all three are fired, and when they are complete, the results are merged into data ready for the table.  And, voila, we now have attachments and roles appearing as hits.
