Add option "is_accessory_cost" on product.template : If the invoice has is_accessory_cost services but no regular product -> DES If the invoice has is_accessory_cost services and regular product -> added to the cost of products in DEB
Now allows "pricelist for statistical value" which is not in EUR (the currency conversion will be made from the pricelist currency to EUR)
Usability improvements : - Order for DEB and DES tree view : "the more recent at the top" - distinction between "Information to declare" and "Additionnal information" in intrastat lines
