Please disable tradelanes for NPC ships.

Chasing npc ships, that sail on tradelanes, is pretty much impossible for
players. The gameplay you get is that you chase a ship around a continent. You
almost catch up in the corners and then they sail away from you again. Maybe
at some point you catch up so you can scan, but probably don't have time
pursue & ram them before they have sailed away from you again.

Sure this can be done with the current system but it will require heavy
roboting to make it happen.
