mrp_advanced_operations: Produce Button error on work order.

[Daniel Stenlöv]

When doing a product from the work order and the products to consumed is set to available. The produce button will generate an error if pressed. To fix this error each Product to Consumed need to be manual klicked and set to done state.

The produce button should instead be called fill and when it's pressed a picking/loading/fill window should be shown as a normal warehouse picking list. That list should set each item to done.

Another way to do it is to remove the produce button until all items are set to done or keep the button but show a correct message that the machine isn't filled with the rawmaterial/products. Also add a load/fill button on the Product to Consume form.
