Adding functionality in order to pull captions from Universal Subtitles...

...using cross domain asynchronous calls by retrieving JSONP and then converting it to the supported WebVTT format. This feature keeps video captions up-to-date using captionator with your video plus it does not require having caption files on the server.

Usage: As example a caption track could be provided with src="http://www.universalsubtitles.org/api/1.0/subtitles/?video_url=http://www.youtube.com/watch?v=kmk43_2dtn0&language=en" or src="http://www.universalsubtitles.org/api/1.0/subtitles/?video_url=http://www.youtube.com/watch?v=kmk43_2dtn0&language=fr" or any other language and type="jsonp/webvtt".

Sorry it's taken me so long to get to this!

I really like the idea of specifying a JSONP resource via src.

That said, I've always tried to make Captionator as standards-y as I can, so I might have to massage this a bit in order to make it fit. I'm having a look at how it'll fit into 0.6 too, since I've re-architected it a bit.
