Do not destroy and create new player on video change.

[qubird]

Fix for #46.
Instead of creating a new player, use the current one when it's already existing, loading the new video via YT method loadVideoById

I have experienced this same problem. I didn't know what scope.player.d was, but I didn't want to remove that code in case it was doing something. So I decided that when the player was created I would fill it with something that would allow the check to destroy it in the even that it never gets overwritten or filled with something else.

I added this:

           // I don't know why, but in some cases player.d is missing.
           // It is needed in case it needs to be destroyed.
           //So if it is not there, then I just arbitrarily set it to true.
           if (player.d) {
              console.log("YouTube player.d exists in this object: ");
              console.log(player);
           } else {
              player.d = true;
           }

Directive portion in the function: createPlayer
fix for this where I added:

       function createPlayer () {
           var playerVars = angular.copy(scope.playerVars);
           playerVars.start = playerVars.start || scope.urlStartTime;
           var player = new YT.Player(playerId, {
               height: scope.playerHeight,
               width: scope.playerWidth,
               videoId: scope.videoId,
               playerVars: playerVars,
               events: {
                   onReady: onPlayerReady,
                   onStateChange: onPlayerStateChange
               }
           });

           player.id = playerId;

           // I don't know why, but in some cases player.d is missing.
           // It is needed in case it needs to be destroyed.
           //So if it is not there, then I just arbitrarily set it to true.
           if (player.d) {
              console.log("YouTube player.d exists in this object: ");
              console.log(player);
           } else {
              player.d = true;
           }

           return player;
       }

P.S. - I am sorry is this is a newbie way to respond, but I just signed into git hub in order to post this, and so I am indeed a newbie. Hope this helps.
