[webrtc-pc] Invalid JSON in examples

fluffy has just created a new issue for https://github.com/w3c/webrtc-pc:

== Invalid JSON in examples ==

Many of the examples got changed from  something like 
{ "a" : 1 } 
to 
{ a:1 }
But that is not valid JSON and given much of the examples are JSON passed to other things, I think it would be better if the examples were valid JSON.
