Try a whole bunch of places to figure out if the HLS plugin should activate

Instead of only supporting the src attribute, check options.sources for HLS on init. This means re-implementing something that looks a lot like video.js's source selection algorithm. That's another reason to consider converting this plugin into a tech but I'm deferring that for now.
