Worked around the need of a bounding box for initialization.

I realized just now that, by design, utils/pointInPolygon() just flips the
'inside' argument around even if no known_point is set, tee hee.
Fixed what must have been a typo.
Fixed badly contructed points loop.
Simplified _list/bbox-filter output.

At the end of the day I will only need the geometry id (when applied to
_view/geojson) or bbox and geometry error (when applied to _view/bbox).
Protected relate function against undefined geometry.
