Brett Phipps e21d7109cb Fixed the problem where country abbreviations that match USA State
abbreviations will never be found.

Arizona seemed to be missing from our _realStates set.  It's in there now.

Added a _mapCountries to map 'obviously' debatable country abbreviations.
(Just have uk->gb in there at the moment.  I probably missed a few).
