Update embedded YouTube player

[Vinny]

The current forum embedded YouTube player seems to be outdated since it's the old style player + it does not support 60 fps videos as you can see here. If you check this video on YouTube you are able to notice that the highest quality is 1080p60, while on the forum embedded player it only displays 1080p. I guess there is some way to update this.
