Geocoding functions using MaxMind-Country and MaxMind-City
databases were bundled into a single class. Now there are
two classes, one per usage of database, preventing to load
unneeded data, as well as a utility class for usage of
Locale to convert country-code to country name.
Also, the code now doesn't try to find data for internal IPs.
The MaxMind-ISP database functions have also been added. They
mimic the behavior of MaxMind-City ones.
Finally, a refresh of internal network IPs have been done in
refinery-core IpUtils.

Refactor tried to follow MaxMind naming and separated classes
that read the DBs (Readers) from actual representation of
results (Responses)

We have also consolidated exception handling to Java 8 more
friendly syntax.
