BAN on the same res.partner.bank.
On res.partner.bank, we now use the field 'rib_acc_number' instead of 'acc_number' to store the RIB bank account number.
Fix inheritance of the view 'view_partner_rib1_form' : it must inherit account.view_partner_property_form and not base.view_partner_form !
Add RIB fields to standard tree and form of res.partner.bank (not just the res.partner form view)
Add max size on RIB fields.
Replaced _construct_constraint_msg function by a raise in the check function : it simplifies the code and avoids a double browse on the object in case of invalid RIB.
Constraint now declares all the fields that must trigger the check.
Updated French translation.
