prepare private ip detection - TODO write unit tests
private ip support
Bugfix: current_ip would always use server ip. Breaking API change: CLI usage no longer supported. What will I do with phpunit?
test
Vendor code should not be modified. Filing Bug https://github.com/maxmind/GeoIP2-php/issues/34 for now.
Refactoring ... API now returns empty object instead of null for ease of use.
