As default, make it so units will not path through neutral regions.

If you make it default for the AI to turn off merchant marines going through neutral countries by just changing a 0 or 1 on the default ROE you can accomplish this. This action should fix pathing issues by some manner and hopefully a lot. Also will help the AI tremendously. Especially in the Vietnam war, since France will not go through Russia.

+1. It is annoying for them to path by default through Leningrad to get to the far east, rather than going through the Suez.
