magic: Change magic numbers

Existing ones are boring. Let's switch them into geographical coordinates
of various Russian towns in NNNNEEEE form.

4 digits for a coordinate give us up to 2km of inaccuracy, which is more
than enough to find a town. We cannot use longitude further than 99.99,
i.e. we won't cover the Far East region, but that's OK -- there's more than
enough good candidates even in the European part of the country only.

Feel free to extend.
