Now that report_intrastat_product/service object is stored in database, we don't need the legal_intrastat state on invoices any more, because we will be able to create entry lines for DEB for a repair of equipment under warranty without using a legal_intrastat.
Report_intrastat_type is now only required for DEB -> object moved to module l10n_fr_intrastat_product.
For DEB, the button "regenerate lines" only regenerate DEB lines related to invoices.
Renamed intrastat base module, because it doesn't have France-specific parameters any more.
Add demo data.
