osm2geojson

Waiting on https://github.com/aaronlidman/osm-and-geojson/pull/4 merge and `npm publish` to merge this in. Could work around by switching `require('osm-and-geojson').osm2geojson` to `require('../../node_modules/osm-and-geojson/osm_geojson').osm2geojson` but that's kinda ugly. Closes #129
