Doesn't work with leaflet v1.0

[vladim1]

The js files in the assets folder seems to be deprecated with leaflet v1.0
I get the following error all the time
TypeError: str is undefined
After some searching I found, that this is a version issue
I think it would be a better choice to use bower to get the latest stable version instead of the old one.

When I use

public $js = [
        'https://unpkg.com/[email protected]/dist/leaflet.markercluster.js'
    ];

instead of

public function init()
    {
        $this->sourcePath = __DIR__ . '/assets';
        $this->js = YII_DEBUG ? ['js/leaflet.markercluster-src.js'] : ['js/leaflet.markercluster.js'];
    }

in MarkerClusterAsset everything works fine.
