Traveller Tracker - Select a World

I've had a bit of a time getting back to this - now that school has started my son Bryson has taken over my computer most of the time.

I did manage a bit of time this evening, and the user can now select a world for their ship to be at, based on the sector and era.  I've got the basic plumbing in place now for the actual tracker. The edit screen allows you to directly change a bunch of things. The tracker will be based on your location and jump for where you can go.

Still need to add in the ship cash and a few more things, but slow progress is better than no progress!
