Use path_find() directly in sorde()

Browse source 
Don't compute the distance from the path, use the path cost.  The
actual path is no longer needed, and we can use path_find() instead of
BestShipPath().

Destinations are no longer treated as unreachable when the best path
is longer than 1023 characters.
