Add support for overpass API for objects that does not contain name tag.

[darkshredder]

Currently, The overpass API call that we are using is getting all objects which have a name tag Link. We also need to add a method for getting all objects by adding a checkbox in the UI so that the interface will call API that can contain all osm objects. But the problem is we are using geocodejson format for showing and storing all results but overpass API returns osm results which can be converted to geojson format but not geocodejson for showing results.

Right now we are only getting all osm_ids and then calling nominatim lookup API for getting all result data as it is imported in nominatim but it is not the same with all tags without name. So we need to figureout a way to convert our osm data in geocodejson directly using some tool or we have to create our own one.
