Subject: [PATCH] Bug 31536: Add UNIMARC framework plugin to fetch PPN from
 sudoc.fr

This plugin uses sudoc.fr webservices (isbn2ppn, issn2ppn, ean2ppn) to
search a PPN using ISBN, ISSN or EAN as search criteria.
The plugin expects than ISBN is in 010$a, ISSN is in 011$a and EAN is in
073$a.

Test plan:
1. Configure the default MARC framework so that 009 uses this plugin
   (unimarc_field_009_ppn.pl)
2. Start creating a new bibliographic record
3. In the editor, write "0195141156" in the 010$a input, then move the
   focus out of the input (by pressing Tab, or clicking elsewhere on the
   page)
   The 009 field should be automatically filled with "06735209X"
4. Empty the 010$a input, then empty the 009 input
5. Write "2262-4694" in the 011$a input, then move the focus out of the
   input
   The 009 field should be automatically filled with "166197947"
6. Empty the 011$a input, then empty the 009 input
7. Write "9782070424597" in the 073$a input, then move the focus out of
   the input
   The 009 field should be automatically filled with "151662983"
8. Empty only the 009 field, keep the same value for 073$a and save the
   bibliographic record.
9. Edit the same record, you should have an empty 009 field and 073$a =
   "9782070424597".
   Click on the 009 field input, it should be automatically filled with
   "151662983"
