Bug 8992: Interfacing with the Idref webservice

Bug 8992: Interfacing with the Idref webservice

On the detail page (in the opac), if the biblio comes from the Sudoc,
you must have a link (on the right of the author link) which open a popup with
informations about this author (publications by role).

To test:

1/ Switch on the Idref system preference

2/ Simulate a SUDOC record:
  Fill a 7..$3 field with a ppn (032581270 for example).
  Fill the 009 field with an integer

3/ Go to the opac detail page of this notice.
You should see the IDREF link.
If you click on it, a popup displays a loading icon and after a few
seconds (depending of the productivity of the authority :)), a list of
roles. For each role, a table displays all his corresponding publications.

4/ On the right, you have 2 links: 1 for a koha search for this result
and 1 for a SUDOC link
