Demo page for constraints and stats

I decided that it was worthwhile spending some time coding up an example 
of use of constraints and stats in connection with getUserMedia and 
PeerConnection. Now the result is out.

The page here:

https://webrtc-demos.appspot.com/html/constraints-and-stats.html

allows you to set some constraints before hitting "Capture" to get the 
camera, or "Connect" to send the picture through a (local) PeerConnection.

At the moment, none of the published Chrome versions care what you set, 
but as they roll out, I hope this page will allow people to easily see 
what their picture looks like in various resolutions, bitrates and 
framerates.

The source tree is here:

https://code.google.com/p/webrtc-samples/source/browse/#svn%2Ftrunk%2Fdemos%2Fhtml

It's VERY simple HTML and Javascript. Changes can be expected at any 
time, randomly.
I hope it'll be useful!
