Bug 8948: Display MARC 787 relationship field

This field is defined similar to 775, as a related work:
https://www.loc.gov/marc/bibliographic/bd787.html

This patch adds a display of this field, linking to the referenced record as
the 775 does

It also tests for 580 field, and displays the text there if present, using the
787 a and t subfields otherwise

To test:
1 - Edit the default framework to make 787atw and 580a visible in editor
2 - Add a 787 to a record:
    $aThe ideas behind the chess openings
    $w2470231
3 - Confirm there is no display
4 - Apply patch / restart all
5 - 'Other related works' now shows
6 - Link should be using title of record
7 - Set system preference UseControlNumber to Use
8 - Reload details, link should now use control number
9 - Add a 580 to the record:
    $a This is a friendly work to this one
10 - Confirm the text of the link now displays the text etnered above
