Added country meta to upgrade routine
* Forthcoming country checkout localization pr will be able to change the label for a region to something appropriate to the country selected.  So for the USA we state will show, and Canada can show province, other countries can be added.  Now my Canadian friends can stop yelling at me when it does not show the right label.

*Also added some phpdoc headers
Changed region meta key from "region_is_called" to "region_label"
Taxes class uses countreis classes for geo information
Don't default country and region on forms
* The change removes the defaults to base country and region
* A "please select a country" or "please select a {region} placeholder will be added to the dropdowns.
* If a country or region is not current for the user the please select message will be the default
* the country meta value "region_label" is used to form the please select message for a region
* if a region_label meta is not found the default wpsc string "state/province" is used
* When dropdowns are created there is logic to be sure an HTML element id is not re-used.  If a duplicated where to happen the string '-2', '-3'm etc would be applied to element ids after the first element.
* The drop downs will default to the one country in the lsit if there is only one country in the list

** Also... **
* Added ability to define meta value defaults for WPSC_Country class meta properties.  Used this new feature to manage the default from "region_label".

Localization of WPeC vars is not more explicit
* The loop that was taking the localized admin js vars out of the localization structure and putting them into the window contect has been replaced by explicit assignments.  Although it is a little more code than the prior loop it should now be easier to see what is happening.
* For localized js vars added after 3.8.14 three utility functions have been provied to access localized vars

Not stoked on this as a resolution for issue # 5 on #950, but it does seem to do the trick.  It's passable, but the root issue requires more investigation.
Resolve some undefined index errors.
