Add support for checking if audio is played in a page.
Add support for checking if audio is played in a page, as well as the ability to (un)mute the audio. Modify demobrowser example to show (muted) in the tab title, if the tab is muted, or (audible) if there is audio playing in the tab. Fix HTML5 audio/video (un)mute to also work.
