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"
Update latest stable version in readme.md.
Deprecate wpsc_google_shipping_settings().
Deprecate  in wpsc_shipping_region_list(), as it is not used.
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.
