Added some new cities and modified the MN tour.

I added Brainerd, Grand Rapids, and Moorhead, and modified the Minnesota tour to:
 * Use Moorhead instead of Fargo (so all the cities are in Minnesota)
 * Use Grand Rapids instead of Minneapolis, which gives us a more central location and makes the TSP problem a bit more interesting. We were going through MSP on almost any route anyway, so "forcing" it didn't make a lot of sense.
