Dev

This is my first Pull Request on any project, so forgive me if I've made a mistake. 

This new class extends the YouTubeBaseActivity for the YouTube API v3, so that you can use a YouTubeVideoView in your activity, and still have an ActionBar that works on pre-4.0. Hopefully you'll find this a useful addition to the library.

The YouTubeVideoFragment unfortunately doesn't extend the support library Fragment so can't be used inside the SherlockFragmentActivity just yet.

Regards,

Andy.
