Not every youtube-link contains a video #215

A youtube-link does not have to be a video-url which contains a ?v=.
But subway doesn't consider this case.

e.g. http://www.youtube.com/results?search_query=do+the+harlem+shake

My 1 minute fix, which was only tested on the above case, for /assets/js/utils.js line 41ff.

//Look for embeddable media in all the links
      for (var i=0; i<links.length; i++){
        var href = links[i];
        //Add embedded youtube video
        if (href.search('http://www.youtube.com') > -1) {
          var video_id = href.split('v=')[1];
// my 'fix'
          if (video_id === undefined) {

While that works, it leaves out the (rare) case where someone uses a short youtube URL. Here's the method I use:

// Get Youtube ID out of a URL
testYoutube: function( url ){

    var id = url.match( /(?:youtube\.com.*[\?&]v=|youtu\.be\/)(.{11})/i );
    id = ( id )? id[1]: id;

    return id;

ae77502 should support short youtube urls (youtu.be). I tested http://youtu.be/WF34N4gJAKE locally and embed worked as expected.
