Update some error messages
Update translation files and FR translation
Include sepa_export in gen_args
Factorize more code between SDD and SCT
Fix view of payment lines
The modules account_banking_pain_base and account_banking_sepa_* are now fully PEP8 compliant
- convert accented chars to ascii chars (via the unidecode lib)
- use "PrvtId" instead of "OrgId" in the XML
Use the sequence of payment.order as the "Message identification" of the XML file (advantages : it is unique, users can easily customize the sequence and users can easily find the payment corresponding to the "Message Identification" in OpenERP). It is also used as the Payment Identification, combined with the sequence type.
Use the sequence of payment.line in the "EndtoEnd Identification" field.
Reduce flake8 warnings.
