sale_credit_limit by Alexis de Lattre

This is a big blocker. I can see companies complaining a lot with this.

What if the customer is willing to pay in advance for this order? Wouldn't you let the company to do business in this case?
What if the credit management team reviews this order and considers that this order should be accepted on an exceptional basis, but don't want to increase the credit limit? An user with proper authorization should be able to release the order, I think.

Both checks are considered in https://github.com/OCA/sale-financial/pull/9.
