Export a symbol's part data as hidden attributes of its DXF block (#1339)

Browse Source 
With symbols as blocks, every non-empty information field of a symbol
(label, manufacturer, reference, supplier, quantity...) is written as a
hidden attribute of its INSERT, tagged with the field's name. A CAD
program can then list the parts from the drawing, as with AutoCAD's
attribute extraction; hidden, they change nothing on screen, in any
reader. A field already written as a visible attribute (with
--dxf-attributes) is not repeated. The label formula is left out: it is
how the label is made, not part data.
