fixed broken kml support

@leCradle pointed out that commit a172b288da7a4fb5f76c11a751d34d8bdfc43ced (https://github.com/jonatkins/ingress-intel-total-conversion/commit/a172b288da7a4fb5f76c11a751d34d8bdfc43ced) broke support for kml files

This patch restores the original kml support, but still keeps styling support for geojson
