geoiplookup.py fails un-gracefully for ipv6

[Riot]

Traceback (most recent call last):
  File "./geoiplookup.py", line 50, in <module>
    print u"OK;{status};{query};{countryCode};{country};{regionName};{city};{zip};{lat};{lon};{timezone}".format(**data).encode("utf-8")
KeyError: u'countryCode'

It should either fail gracefully and not attempt to parse ipv6, or it should preferably detect ipv6 addresses and direct them to a suitable ipv6 geoip api.

The API temporarily does not support IPv6, but the script fails gracefully since commit 1397dc2
