[talk-ch] GWR extracts and address stats

I've updated the underlying GWR data on http://qa.poole.ch/addresses/ch/ to the version from the 6th of this month.

The data now contains 2'016'654 a small increase over 2'015'744 since I last updated the data in May of this year.

A further general reminder, we are still missing a substantial number of street (nominally ~17'000) and place (nominally ~25'000) names, while 3'403 of these are simply minor spelling differences (for example due to Geneva changing the capitalisation of street names in the data), the majority are real.
