According to https://download.geonames.org/export/dump/readme.txt:

alternateNamesV2.zip : alternate names with language codes and geonameId, file with iso language codes, with new columns from and to
alternateNames.zip : obsolete use V2, this file does not have the new columns to and from and will be removed in the future

alternatenamesV2.txt also has a consistent formatting which allows us to easily parse the historic names and ignore them when building the database.

Closes #19 (also the mentioned Helsinki issue), #20.

With the updated database I also verified that #4 gets resolved.
