Nutritional Info Stock Lot

This module adds a Nutrition tab to the lot/serial number form in Inventory. There you can list the nutritional values for that specific lot, with one line per nutritional type and its value.

When you pick a product on the lot, the lines are filled automatically from the nutritional values configured on that product. You can then change the values for that lot, so the lot keeps its own information instead of the product's.

A control prevents you from adding the same nutritional type twice on the same lot: Odoo shows an error if a type is repeated.

A new report named "Nutritional Info" is available on lots. It prints the lot name and product, and shows the nutritional table, taking the lot's own values first and falling back to the product's values when the lot has none.

In Inventory settings, a new "Nutritional Values" menu gives access to the "Types" configuration, and stock users are granted access to the nutritional type and value records so they can maintain them.

The module works together with the nutritional information and stock modules, and touches the stock.lot model plus a new lot-specific nutritional value model.
