Control picking front-facing or back-facing camera easily

[cdata]

As a camera app author,
When I implement camera switching,
I want unambiguous control over which camera to use,
so that I can pick the right camera at the right time.

It also makes sense to switch the icon between camera-front and camera-rear to indicate which camera is in use. 😉

The request is for unambiguous control by the app author (e.g., person configuring the element), not the app user (e.g., person interacting with the UI). So it is asking for an API that makes this easier.

@cdata @bicknellr Is it fixed by #21? If yes, could you please show/add how to use it in/to the demo (demo/index.html)?
