toGeoJSON.kml is not a function ?

Hi,

I am getting error "toGeoJSON.kml is not a function" in Widgets.js.
at this line

`var geojson = toGeoJSON.kml(dom);
`
```
define(
[
'libs/togeojson',
...
....
],
function (toGeoJSON,
...,
...) {
importGPXorKML: function (event) {
debugger;
var content = event.target.result;

try {
var dom = (new DOMParser()).parseFromString(content, 'text/xml');
}
catch (err) {
this.message("The input file is not a file " + this._current_file_extension + " valide.");
this.loading(false);
}
this._createResultLi();
if (this._current_file_extension == "gpx")
var geojson = toGeoJSON.gpx(dom);
else {
this.registerKmlStyles(dom);
var geojson = toGeoJSON.kml(dom);
}

this.addGeojson(geojson);
}
}
```

Start in Widgets.js at the AMD dependency on libs/togeojson and reproduce the KML path that calls toGeoJSON.kml(dom). Inspect how that dependency is loaded and what value it provides, then verify the KML import completes without the reported TypeError.
