Sale Single Attribute Value Display

By default Odoo hides attributes that have only one value from the product description shown on a sale order line. This module changes that behaviour so the single value is written out.

• It affects the description that is automatically filled in on a sale order line when a product is selected.
• The description is built by the product's multiline description method, which now asks for single-value attributes to be included.
• The attribute value name is then added to the combination name, so the customer sees the full attribute wording on the order line.

There are no new menus, buttons, reports or settings. The change is automatic and applies wherever the sale order line description is generated, for example when adding a product to a quotation or sale order.

The module extends product.product and product.template.attribute.value. It only changes how the description text is composed; prices, stock, taxes and other sales rules are untouched.
