Loading sequence 3

Previously mentioned bugs (in  last commit) are fixed, as well as
various bugs related to the map text / map button, and status updates.
One bug remains in map: buttons should say “close” until a selection
has been made.  Also need to test for the ability to click after making
a selection (lock it out).  Also need to change color of selected
country.
Loading 4 and map changes

Changed some loading sequence css to make it work in iOS.  Fixed issues
mentioned in previous commit.  Elected to allow user to click again on
the map if they wish to:  map re-centers and re-labels, adjusting the
state changes to reflect the new selection.
Last commit before map changes

Dropping support for tablet and phone for now.  Last commit before
attempting to move to databased map generation: one map, starting from
the continental world view that can drill down to region then country,
using mongo db data.
