Auto Geocoding of partners

Automatically geocode addresses using http://www.geonames.org/ api. We use this API because it is free and has little data usage restriction. However the API requires a valid username. The username must be specify in the System Parameters under the key 'geoengine_geonames_username'. The limitation is that address is localized by city not by street. For more precize localisation you have to use a non free API. Google maps APi limitation exclude the use of geocoded data in OpenERP. You can contact Camptocamp if you need to create a specific geocoder or acces geocoding services.

Technical notes: PostGIS must support projection (proj4) We use postgis to do the reprojection in order to avoid gdal python deps.
