sort by distance and category

This is till open, since I never bothered to actually truncate the list of places. Currently it's useful to see even the non-relevant places to get a feel for the landscape.

This is sort of the under-the-hood adjunct to #41

Here's the current implementation:

  CASE category
  WHEN 1 THEN -- continent
    relevance := 0.35;
  WHEN 2 THEN -- country
    relevance := 0.45;
  WHEN 3 THEN -- region
    relevance := 0.45;
  WHEN 4 THEN -- county
    relevance := 0.5;
  WHEN 5 THEN -- locality
    relevance := 1;
  WHEN 6 THEN -- neighborhood
    relevance := 1;

wouldn't it be nice if this scale was continuous?
