Subject: [PATCH] Extend nearest-polygon fallback to all countries, not just
 Scotland

Points in the sea near England (or any other country) now fall back to
Polygon.nearest() to find the closest admin_level>=7 polygon on land,
giving a specific civil parish or district instead of just returning
England (Q21).

Closes #30
