Cache/Import geonames data for all countries..

[dberesford]

It's time to do this, we know if will take ages to run so lets run it once and keep all the cached data so we can quickly populate staging and production. Script should do it on a country by country basis (I think the existing one already does?)

I need to put some sleeps into the script to lower the CPU usage then run the script again and export the data from the DB into a INSERT INTO ... sql kind of script.
