Port Loren Starport - rework - short north

This is a rework of Dominic's map <<node,6399>> that I
reworked with the same colors and style I used on the recreated Port
Loren map.  I added shadows to this version assuming that the short edge
was north and the shadows matching the Port Loren map.  I also changed
the direction of the arrows on the large road to match the Port Loren
map.
