Protocol Relative URLs

Is it possible to use protocol relative URLs in the plugin?

On https sites some browsers block loading of http resources however this plugin forces some http resources such as:

https://cdn.bootcss.com/jquery.qrcode/1.0/jquery.qrcode.min.js

Could this be ammended to:

//cdn.bootcss.com/jquery.qrcode/1.0/jquery.qrcode.min.js

So it would take the protocol of the website it was being loaded from?

Great plugin BTW!
