Product Imports: Update Archived Products From A CSV

A product import can now update a product you have archived. Include its SKU in the file and the row is applied to the archived product, the same as any other row. Before this, a row matching an archived SKU stopped the import.

The row also decides where the product ends up. Mark it as archived and it stays archived with your changes saved; leave that column clear and the product returns to the active catalog.
