Patch from David Christensen to add support for fetching jacket images from Open Library:

Hi folks,

At a suggestion from the #OpenILS-Evergreen IRC channel, I'm putting this out there :-)

This is a patch to /openils/lib/perl5/OpenILS/WWW/AddedContent/Amazon.pm (it probably makes sense if it were to end up as OpenLibrary.pm, or some such) that enables getting book cover images from OpenLibrary (see http://openlibrary.org/dev/docs/api/covers for details on the OpenLibrary API).

A little comment section at the top shows the two changes that need to be made to opensrf.xml as well.
