Extra blank line

Nit: another blank line.

And one more.

Could you move these bits up into the if statements above that do the same thing? Or is it that if there is a videoConstraint that you fail, you never want to have created the audio source?

Good point, I will change this (and remove the nasty blank lines).

Thanks!

 "@interface WebView (WebViewUserMedia)" is a function call?
