use the iframe Youtube player when possible

[steren]

Youtube players used should be the "new" Youtube player (that uses an iframe, not the embed flash object).
With this new player, Youtube decides to une a flash version of an HTML5 version itself.

On my project, I changed this in the video.youtube element of the iOS adapter (that I use for Android too):

  // options.url : need to be the ID of the Youtube video
  // the src should be like src="http://www.youtube.com/embed/khWXdkryBE4?rel=0"
  this.htmlEl.innerHTML = '<iframe width="' + width + '" height="' + height + '" ' + 
      'src="http://www.youtube.com/embed/' + options.url + '?rel=0" frameborder="0" allowfullscreen></iframe>';

I guess this is obsolete since the new framework based on backbone.js is on its way.
