Installation changed

Module completely overhauled to introduce support for Maxmind GeoIP2 databases.
The way to install the module has changed:

1. Enable this module as usual
2. Install one of the Maxmind php APIs:
   

   GeoIP2:

   • Using Composer:
     Install the library using composer in [path_to_drupal]/sites/all/libraries/GeoIP2-php
     *nix Commands:

     mkdir [path_to_drupal]/sites/all/libraries/GeoIP2-php
     cd [path_to_drupal]/sites/all/libraries/GeoIP2-php
     curl -sS https://getcomposer.org/installer | php
     php composer.phar require geoip2/geoip2:~2.0

   • Using phar package:
     Download the latest phar package:
     Place the file geoip2.phar here:
     sites/all/libraries/GeoIP2-phar/geoip2.phar

GeoIP - Legacy:
1. Download from: https://github.com/maxmind/geoip-api-php
2. Extract to [path_to_drupal]/sites/all/libraries/geoip-api-php
3. Make sure you've a path like [path_to_drupal]/sites/all/libraries/geoip-api-php/src
3. Download one of the GeoLite database files (matching the API):
   GeoIP2: http://dev.maxmind.com/geoip/geoip2/geolite2/#Downloads
   Legacy: http://dev.maxmind.com/geoip/legacy/downloadable/
4. Create the directory path_to_drupal/sites/all/libraries/geoip and extract the database
   file into this directory.
   You can use other locations too e.g. to share a database with varnish or
   other tools - to do so you can configure the path to the database to use in
   the module configuration (admin/config/system/geoip).
