Live Channel - Youtube

Allowing for the video to be refreshed with the new song each time the
video is ended using the YouTube iFrame JS API.
Youtube API Addition

Added pulling of youtube videos via Ajax requests of YouTube_ID.php, to
get the newest songs youtube video ID.  It then checks if the video
currently playing as ended. If ended, then the AJAX is polled again to
see if a new song is played, which is then loaded into the youtube
player. Thus creating a video radio via twitter feed.
YouTube API Request

ID, and duration time.

'convtime()' funciton. Utilizes Google PHP Framework.
