account_fr: Track the amount invoiced in sales outside Europe
This data is needed on the VAT declaration\. So instead of dropping \
the tax in the \"Ventes hors communauté\" tax rule\, we map them to \
a new tax with a 0\% rate which records the base amount in the correct \
tax code \(0032 for the invoice\, 0039 for the credit note\)\. \
\
Suggested patch in review10961002\. Requires tax code created in review8971002\.
