Postal code dump import

[Ep0chalypse]

GeoNames also provides a dump of postal codes here http://download.geonames.org/export/zip/ would would be nice to include in this.

Just included Wicked0ne.
Now the dump process downloads a zip file with all that information but be carefull as It takes a looooooong time to import ;-)

Wouldn't it be nice at this point if we could provide some mechanism to import just the information for a given country or list of countries?
