improve usage of planned orders. - The description of the planned order includes the topmost requirement that caused the planned order. This makes it easier to trace, for example, what planned orders has a given sales order generated. The description of the planned order is passed on to the Manufacturing Orders / Purchase Orders / Transfers as the origin, so it can be possible to search for PO's / MO's that were originated as a result of a given sales order, for example.

- The MRP Inventory tree view is improved so as to add a button to allow you to
  jump to the planned orders.
