Waiting for this merge!

That looks good, thanks a lot.

I'll bump version to 0.0.5 and publish to registry once I get the chance, thanks again.

Shouldn't the _uri template (livereload.js at line 141: this._uri = "ws://" + this.options.host + ":" + this.options.port + "/livereload";) be changed to secure protocals as well in this case?:
this._uri = "wss://" + this.options.host + ":" + this.options.port + "/livereload";
