Sarah Hoffmann 8ed096f938 speed up reverse lookup of place nodes
Add a special index that contains the place nodes buffered by their
respective area according to their search rank. This replaces the
maximum area search for place nodes and reduces drastically the number
of place nodes that need to be retrieved.
