Stock Move Priority Picking Assign

This module changes how transfers are created automatically when stock moves are assigned to a picking. Instead of always using the default priority, the new transfer inherits the priority of the stock move(s) it is created from. If several moves are grouped together, the highest priority among them is used.

A new option is added on the operation type form (Inventory > Configuration > Operation Types), under a "Moves priority" section: "Group moves per priority". When checked, moves with different priorities are no longer merged into the same transfer; each priority gets its own transfer. When unchecked, moves are grouped as usual and the transfer takes the maximum priority of the moves.

The module touches the stock.move and stock.picking.type models. It relies on the priority field provided by the stock_move_manage_priority module. No new menus, reports, emails or scheduled actions are added; the only visible change is the new checkbox on the operation type screen and the automatic priority transfer during picking assignation.
