Bugfix: Oh, sectors are *forty* hexes tall?

Sharp-eyed user "alx alx" noticed that a search for "Herod" wasn't finding Hinterworlds 1940. I was out of town so I couldn't look at the code, but I played around and discovered that no worlds in the xx40's were being found by a search!

Turns out to be a simple off-by-one error in the enumerator code - I had a "y < 40" where there should have been a "y <= 40". Fixed! Ω
