add region name to location tokens

Locations are streets in town usually. But for small villages without named streets,
village name (region) is added as virtual location to our location index.
Address points are linked by "addr:place" tag to the place (region).

So, to be able lookup address points just by phrase "Village 123",
we add region name to location search patterns.
`We would force users to use pattern "Village Village 123" otherwise.
