Add geolocation-based filtering #19
Description
Feature request from WP support forums: https://wordpress.org/support/topic/great-feature-request/
Introduce a feature to white- or blacklist requests from certain countries from tracking.
To achieve this, a geolocation service has to be integrated and processed during live filter - cron cleanup is not possible here because the IP is not saved.
Such service might be MaxMind GeoIP2 which provides a nice PHP API1. Keep in mind the latest changes for database usage2.
