Guess partner on import of statement lines

This module speeds up bank statement import by guessing the partner (customer or vendor) for each imported transaction, so you do not have to select it manually.

• For every transaction that does not already have a partner, Odoo looks at the transaction reference and label.
• It searches for a matching invoice using the invoice origin, reference or number, and for a matching sales order using the customer reference or order number.
• If a match is found, the partner from that invoice or sales order is placed on the transaction.
• If the partner found is a child contact, Odoo uses the parent company contact instead, so the correct business partner is used.

The feature works inside the standard bank statement import process; there is no new menu or button. It only changes what happens automatically while importing a statement file, and it touches account.bank.statement.import, account.move and sale.order.
