Bower-integration is missing

[heiglandreas]

Is there a plan for a native bower-integration? I've already created a fork that implements this library as a bower-component and I'm willing to maintain that but it would be easier for all when you'd implement that. I can provide the necessary files as pull request if that would be helpfull.

The bower integration can be found at http://bower.io/search/?q=overlapping_marker_spiderfier-leaflet
