Moved Geocoder to google_geocoder.php
This was done because it was no longer working (returning a 403) error, I did
not workout WHY it gets a 403 error but decided to port the default
geocoder service (geocode.php) to another service. This is being left in the
code base as a reference really. refs: geomoose/geomoose#29
Created geocoder.us geocoder, refs: geomoose/geomoose#29
Merge branch 'master' of https://github.com/geomoose/geomoose-services
