New mapping 1

Added countries and regions to db for North America.  Worked out how to
programmatically create and show a region map.  Normal game
functionality temporarily hijacked so that I can use the app to work on
the maps.
Drill-down maps from db records

Data is incomplete and states / updates are not fully implemented, but
drill-down mapping is working from the database.  All maps, whether
world, continent, region or country all use the same amman map script:
worldLow.js.  The areas object is constructed on the fly using JSON.
