First-level administrative units: State names and ISO codes added

We just added "first-level administrative divisions within a country" (usually called states or provinces by regular folks ;) to the API's JSON response as an explicit attribute. See stateName for the colloquial name and the corresponding computer-friendly ISO code in stateCode; note that one of both may be empty for smaller nations when no such civil divisions exist or when ISO hasn't assigned them a code.
