Ok, I finally made the change to the code I have been pseudo-promising for
months concerning maps

.
In short, you can now make maps anywhere, with the rules being as follows:
1) Higher level navs ==> better chance of success.
2) If given a way off the ship, the nav will use it. If that way off is
closed, the process is aborted and the map is wasted.
3) If no way off the ship is provided, the nav will do what he can to make the
map, but at a GREATLY reduced chance of success. The ship must be
anchored/landed though, and if the ship raises anchor of launches, the process
will abort and the map will be wasted.
Ok, have at it!
