Hi @lat9

Some feedback from my translations.
I noticed that the language files for ot_coupon.php, ot_gv.php, and checkout_confirmation.php are from pretty old versions of ZC. Probably good to include modified versions from the latest 1.5.6c.
In particular, checkout_confirmation has some old text about out of stock items that can be put on backorder. As I understand it this is now in the main english.php file.
Hope I did not mess up something and get this wrong.
