Better Navigation, and Help Topics

Today I added improvements to how you can navigate about the world.

You can see neighbor locations, but you will only see detail once you have visited that neighbor.

The location is described in part by the XY position.

In addition, I put in the ground work for there to be help topics for when you hit F1.

At the moment, I only have help topics for the navigation screen, but this makes adding topics elsewhere less work, and the plan is to get the rest of the screens responsive to F1.
