Shaka namespace needed

[greenya]

Hello guys.
We (me and @mrlika) managed to make all work without this change. We have used "external" version of your library (which comes without bundled ShakaPlayer and relies on global "shaka" included before the library). This way our library and your one uses same "shaka".

Maybe simply add a getter, like we did for HLSJS playback, for example :

  static get SHAKA() {
    return shaka
  }

And the player instance should be available with the shakaPlayerInstance getter. (if created)

Thanks you two =) I'll bring @towerz and @vagnervjs I think @kslimani idea's seems pretty solid.
