Update api.timelapse_fn, use track_geom as geometry instead of track_geojson as geojson. x10 faster.

Browse Source 
Update api.export_logbook_geojson_fn, output as JSONB as per best practice.
Update api.export_logbook_gpx_fn, dynamic from track_geojson on 'geometry'->>'type' = 'Point'.
Add api.export_logbooks_gpx_fn, export multiple logs in a GPX format
Add api.export_logbooks_kml_fn, export multiple logs in a KML format
