Show lines of zero thickness in GAL 

If a line has zero thickness, use the outline thickness to draw it.

This avoids having invisible items on the PCB that could still end up in
outputs, or "losing" an item by setting thickness to 0.

This only affects GAL drawing routines, the PCB data structures are not
affected, so any outputs will be the same.
