Title: Exposes the setVolume, mute, and unMute methods of the underlying iFrame API

I needed these methods exposed for a project I'm working on, and thought that since I'd gone to the trouble (at least 5 minutes ... :)) of adding them in I might as well share them back; it's about as simple of a change as it gets but if you've got reasons that these volume methods weren't exposed before, no worries!
