Stock picking type - Restrict users

This module adds an "Assigned users" field on each operation type (for example Receipts, Delivery Orders, Internal Transfers). A warehouse manager fills it in on the operation type form; the field is only visible to users with the Inventory Manager role.

A new security group, "User: Assigned Operation Types Only", is created. When a user belongs to it, record rules limit what they can see: - They only see operation types where they are listed as an assigned user. - They only see transfers (pickings) whose operation type is assigned to them. - Users with the standard Inventory user role keep seeing all operation types and all transfers.

The Inventory menu and the Receipts and Delivery Orders menus are made available to this new group, and several action buttons on transfer forms and on product forms are shown to it as well, so assigned users can still do their daily work.

Access rights are also granted for the stock objects needed to process transfers, such as transfers, moves, move lines, lots, packages, quantities, scraps, returns and replenishment options. The module touches stock.picking.type, stock.picking, stock.move, stock.move.line, stock.quant, stock.lot, stock.package, stock.scrap, stock.return.picking, product.product and product.template.
