chore(HTML5): break AudioObject to its own vendor

[dobrite]

Fixes unmounted Audio objects hanging around. It also cleans up all the conditionals in HTML5 and moves all the complexities of handling the audio object to its own component.

I inherited from HTML5. I'm open to a different way of code sharing, but I felt this was the most direct and understandable.
