Subject: [PATCH] Bug 4305 Get Amazon book covers for ISBN13

The way Koha get book cover from Amazon doesn't work from biblio records
having ISBN13 because Amazon expect an ISBN10. This patch transforms
ISBN13 into ISBN10 before sending it to Amazon.

Warning! On some devel installations, you will have to install by hand a
new CPAN depency:

  Business::ISBN
