iframe lazyloading #405

Hi,

I have added multiple videos on one site and having some performance issues especially with Firefox. The browser struggles in loading all the iframes at the same time.

It would be helpfull if there is an option to lazyload the iframes only if the play icon is clicked. The loading of the video would take a little longer but the performance would be much better I think.

This would actually be very easy to achieve! Just remove line 731 loadScript('https://www.youtube.com/iframe_api', apiLoaded); And add this block inside the else statement of the constructor in line 59

this.one(this.el_.parentNode, 'click', function (argument) {
    loadScript('https://www.youtube.com/iframe_api', apiLoaded);
});

You could also wrap line 731 in if (this.options_.autoplay) and line 59 in if (!this.options_.autoplay) to make it compatible with autoplay.

For performance reasons, it would be very nice if you cound make this an config option! ... Since it is so little effort to achieve!

Thanks!
