Subject: [PATCH] Switching to address based map generation. Divided to
 subroutines.

The generation was geo: tag based but as there is only one tag per
vcard I switched to address lookup instead.
There are problems with CZ village addresses, and some missing
address tags that has to be added to openstreetmap, but it is a
better longterm solution.
