Added #defines for a changed second flash pixel color to indicate which time zone is being displayed, and re-factored existing code to display the time zone A color.
Updated global time zone values to be bogus, out-of-bounds values by default to make sure the loadTZ() function is performing its function.
Added better debugging for time zone setting code, and fixed debugging code in saveTZ() to reflect that it's saving, not getting the time zone data.
Updated loadTZ() debugging code to reflect that it's loading, not getting the time zone data.
