jcoffey-dev dbf4b9dea4 Use the published board instead of drawing a worse one
Three attempts at drawing this map came to nothing worth looking at. Dividing
the plane by nearest province gives a tidy board that looks nothing like
Europe. Drawing the adjacency graph gives something unimpeachable about the
rules and not a map at all -- circles joined by lines. Fifty-six polygons
placed by eye gives fifty-six islands.

The standard map published with the diplomacy engine is AGPL-3.0, the same
licence as this project, so it can be carried across whole with attribution
rather than approximated badly. tools/map.py extracts the outlines, the unit
coordinates and the layer transform into board.json and can be re-run against
a newer copy. NOTICE.md says where it came from and what is still ours, which
is every colour and every mark drawn on top.

Drawing Europe accurately is real work, somebody did it properly, and they
published it under a licence that invites exactly this. Three days of my
approximating it would have produced something worse than the thing that
already existed.

Clicking still answers with the rules rather than the picture: a shape cannot
say that a fleet on Spain's north coast may not enter the Gulf of Lyon while
one on the south coast may, because both coasts are the same shape.
