[Freeciv-Dev] Example isometric map game

[Jason Dorje Short <vze2zq63@xxxxxxxxxxx>]

I've placed a screenshot into the incoming directory that shows the end
of an isometric-map game.

Most things work in a topology-independent manner now, but not
everything.  As soon as I iron out a few more of the problems I'll
provide a monolithic patch to demonstrate the changes.

Warning: the file is about 1 Mb in size.  I'm not sure if this could
have been avoided.
