Subject: [PATCH] Bug 20212: Use the DT column filtering provided by the
 wrapper

Bug 27402 is adding it, we do not longer need the query_from_filters JS
function.

This patch also remove the filters on the left. As we have DT
remembering the filter on the table we don't need them anymore.

Technical note:
Prior to this patch, the search on biblio.author, biblio.title and
biblio.ean was done by adding hidden columns. Now we are using:
  "data": "biblio.author:biblio.title:biblio.isbn"
to tell the wrapper we are going to build a search on these 3
attributes.

The change in Orders.pm is only formatting to match what's done in
