Search housenumbers with unknown address parts by housenumber term
House numbers need special handling because they may appear after
the street term. That means we canot just use them as the main name
for searches where the address has its own search term entries.
Doing this right now, we are able to find '40, Main St, Town' but not
'Main St 40, Town'.
This switches to using the housenumber token as the name term instead.
House number tokens can get special handling when building the search
query that covers the case where they come after the street.
The main disadvantage is that this once more increases the numbers
of possible search interpretation of which we have already too many.

POIs with unknown addr:place must add parent name to address
The previous behaviour was a left-over from a former version
where such POIs parented to the street. Now that they parent to
places, it should be included.

get additional addresses for rank 30 objects
get_addressdata() now also checks if the place itself has entries
in the place_addressline table and merges them into the results.
Also restrict checking for address tag places to cases where the
name cannot be found in the parent's address search terms. Looking
up all address tags is just too slow.

lookup places for address tags for rank < 30
While previously the content of addr:* tags was only added
to the list of address search keywords, we now really look up
the matching place. This has the advantage that we pull in all
potential translations from the place, just like all the other
address terms that are looked up by neighbourhood search.
If no place can be found for a given name, the content of the
addr:* tag is still added to the search keywords as before.

remove now unused settings related to website
There are two places where the website URL is still used:
for icons, replace the URL with a link to the icon repository
of the UI repo. The more URL now builds the link from the

minor fixes for geometry compuation during boundary ranking
Go back to using centroid when determining if one admin level
is within another. There are cases where boundaries are slightly
misaligned due to mapping errors (not using the same ways in the
relations).
Only declare boundaries the same when they have the same wikidata
tag _and_ have exactly the same geometry. This works around tagging
errors with the wikidata tag, which happen because of automated
edits to the wikidata tag.

detect and remove admin boundary duplicates
The Polish community maps admin boundaries that span multiple
levels by duplicating the boundary relations. Detect this situation
by looking out for matching wikidata tags. The higher ranked
duplicates are then thrown out from the address pool by setting
their address rank to 0.

add explicit bbox contains check
Now that the containment check uses ST_Relate, we need to add

demote admin boundaries for place areas

overhaul address computation
This is a complete rewrite of the selection of address parts to
be inserted into the place_addressline table.
The new algorithm selects for each rank:
* the boundary overlapping with the addressee and contained
in the already selected boundaries of lower rank, or failing that
* the place node closest to the addressee that is contained in
the already selected boundaries and in the influence radius
of already selected place nodes of lower rank
Place nodes that are not contained in already selected boundaries
of lower rank are completely thrown away. All other candidates are
added as non-address parts.

demote place nodes in admin areas
If a place node of city rank and above finds itself in an
administrative boundary of the same address rank, then
increase the address rank by 2. This catches the rather

reasons as towns or villages.
