Sale Margin No Onchange

This module copies the cost of the product on the sale order line when the sale order line is created and it computes the margin amount (in the currency of the order and in the currency of the company) and the margin rate. It also computes the total margin of the sale order (in the currency of the order and in the currency of the company).

I decided to develop this module as an alternative to the OCA sale margin modules because I wanted a small and simple module. The module account_invoice_margin, available in the same Github repository, does the same thing on customer invoices.
