higher penalty for special searches
Adds a general higher penalty for special search term and an
additional one if the term is anywhere but the beginning or the
end. Also housenumbers and special searches together are less
likely.

fix result splitting for last search group
When we are in the final iteration of the search groups, it is not
possible to further delay the results. Unconditionally use the
results with the best rank instead.

give preference to full words in address, too
Full word terms are already preferred for the name part. Adding
only one-word partials to the address, makes it impossible to
give a similar preference for the address part. Each term adds
a rank penalty. The problem here is that we interpret the query
forwards and backwards. Having different penalty systems for
name and address means that the same term ends up with different
penalties and that often leads to interpretations of the wrong
direction being in the way.

improve deadlock detection for various versions of psycopg2
Psycopg2 has changed the kind of exception that is emitted on
deadlocks between versions 2.7 and 2.8. The code was already
trying to catch both kind of errors but because the
psycopg2.errors package is unknown in 2.7 and below, the
code would throw an exception on anything but a deadlock error.
This commit wraps the deadlock handling into a context manager
to avoid code duplication and uses module imports to detect if
the new error codes are available.
Also sets the required psycopg2 version to 2.7 or bigger as
versions below are difficult to test.
