Extend Clips response with video_name and game_name
The clip response already include both id and name -fields for some data -- broadcaster_id/broadcaster_name and creator_id/creator_name.
It would be helpful if the same was true for game_id and video_id, so we wouldn't have to resolve these by making additional requests.
game_name: the title of the game being played.
video_name: the title of the video (stream) that the clip came from.
