Bug 9573: Lost items report - Add the CSV export ability

Finally we add the ability to export the list of lost items.
The items will be export in CSV format using a CSV profile defined.

Test plan:
0/ Apply all the patches from this patch set
1/ Define a CSV profile (type=SQL, Usage=Export lost items in report)
Try something like that to get the same columns as the default table:
Title=biblio.title
|Author=biblio.author
|Lost status=items.itemlost
|Lost on=items.itemlost_on
|Barcode=items.barcode
|Call number=items.itemcallnumber
|Date last seen=items.datelastseen
|Price=items.price
|Rep. price=items.replacementprice
|Library=items.homebranch
|item type=items.itype
|Current location=items.holdingbranch
|Location=items.location
|Not for loan status=items.notforloan
|Notes=items.itemnotes
2/ Use the filters and select items to export
3/ Export the list of items you want and make sure the CSV is correctly
formatted and contains the items you selected

QA Notes:
- I think we should add default CSV profiles for the different "usage",
but I would consider it as a separate enhancement since none of them is
defined yet
- Most of the code to export CSV is no reusable. We should make
Koha::Exporter::Record support CSV export for type=SQL (it only
supports MARC type so far).
