Switched to 'search' where 'match' wasn't really needed.
Removed all /^GeoJSON/ from fields listing.
Shrinked text fields a bit more.
Fixed a lot of poorly written awful javascript.

- "array" is not a type for christ sake!!!
- doc._rev is irrelevant for _updates.
- doc.type should be presumed in _view/geojson but GeoJSON or GeoJSON_clone
  shouldn't.
- I like javascripts comparision of different types. For instance I don't care
  if obj.field is null or undefined, so 'if (obj.field==null)' works fine for
  me. However if this is reduced to 'if (obj.field)', unpredicable results
  ensure if obj.field is 'false', '0.0', '"false"' or something. As soon as I
  am pretty damn sure that I am dealing with EITHER an object or null and there
  is no possible way that this could be a number or bool, only then the reduced
  expression is acceptable.
Scratched the geojson reduce function.

Due to the size limit of reduce's return value (900 bytes or something) I am
unable to use it to collect docs in it that share a GeoJSON object. I might
turn it off by posting to /_config but then I'd have to do so in every local
installation (and assume admin party etc. NO WAY!!!!).
Designed a draft for a spacial _list/bbox-filter.

This one accepts parameters as request body, because I won't use it much with
curl when I don't need to test it. I.e. it is POST _list/bbox-filter/geojson
that also sounds like a sentence. I see that the filter might be switched, but
the geojson part is pretty much set in stone. Parameters are:
- bbox: four-element array [x1,y1,x2,y2] of min/max coordinates,
- limit: stop filtering after this many GeoJSON items,
- keys: array of GeoJSON ids to restrict filter to. This is of course just
  CouchDB API, but I foresee it as as powerful tool to lower the server load by
  providing previously sorted GeoJSON ids.
Output reads {"doc_18b":{"docs":[{"type",etc.}, more docs],"GeoJSON":{...}},
more ids} so it is the GeoJSON id, then docs and GeoJSON, then the next id.
Stashed split array to speed up _list/tabulate.

Also it failed on every 2nd occasion and was poorly coded.
