Removed old zones from Latvia (country_id = 117),
Added New zones.

They are changed already since March 30, 2010 according to [http://likumi.lv/doc.php?id=207512](http://likumi.lv/doc.php?id=207512)

Note that the zone codes are not postal codes. They are 'official' zone codes used for accounting.

The only problem is - i don't know how to make an update script, as the old zones and new ones cannot be mapped - there are more new zones than old ones.
