My version of the allow-aircraft-to-goto patch. It allows movement
anywhere as long as we have movement points to return, and allow
attacks, even suicidal ones. Of course, it is still not perfect, since
for example fighters cannot goto to "see" the enemy and then attack it,
but I think it is a highly useful band-aid before we come up with
something better.
