Subject: [PATCH] Add 'specified_cable' field for BOM generation

There is no obvious way of specifying exactly which cable type
(manufacturer, part number) to use for a given cable, which is useful
for BOM purposes. Add a 'specified_cable' field to the Cable class to
remedy this, and render it both in the graph and the BOM.
