Product Form Purchase Link

This module makes it easy to jump from a product to everything that has been bought for it.

On both the product variant form and the product template form, a new "Purchases" stat button appears in the button box at the top of the screen, showing the purchased quantity. Clicking it opens a list of purchase order lines for that product.

The list opens already filtered on confirmed purchases (Purchase Orders), and two extra filters are added to the search panel of purchase order lines: - "RFQs", which shows draft, sent and to-approve requests for quotation. - "Purchase Orders", which shows confirmed and done orders.

No new models, fields, business rules or scheduled jobs are added; the module only adds views, a button and two window actions on product.product, product.template and purchase.order.line.
