Bug 10573: French translation for printing a basketgroup

If you want to print a basketgroup with pdf format, it will be in
English.  The pdf is done with layout2pages.pm or layout3pages.pm,
which call layout2pages.pdf or layout3pages.pdf.

This patch adds layout3pagesfr.pm in src/acqui/pdfformat/ which
calls layout3pagesfr.pdf.

And adds in basketgroup.pl the check for layout3pagesfr
To use it you have to change the systempreferences to  pdfformat::layout3pagesfr

Comment: Work as described, koha-qa reports some tab errors.
Corrected in a followup.

Please, always add a test plan, it's easier to test.

Test:
1) apply the patch
2) change syspref OrderPdfFormat to pdfformat::layout3pagesfr
3) select a vendor
4) create a basket group (empty works)
5) close basket group
6) print basket group
7) PDF is in french

This works nicely, although it would be better if we could
find a more general solution to make the templates editable
and translatable.
