overhaul address computation
This is a complete rewrite of the selection of address parts to

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.

restrict postcode searches to postcode in first token
In structured queries we should only assume that it is
a postcode search when only the postcode and optionally
the country is given. If any other term is present, it
is better to avoid the search for postcode as it yields
too many bad searches. Given that the terms in a structured
query are ordered, this means that the postcode must be
the first token just like in the unstructured query.

We can't use getNearFeatures() to determine the parent of a
