Support for native Flash Player 11 JSON Object

[ElliotChong]

Replaced the old AS3 JSON library reference with the new native JSON Object introduced with Flash Player 11.

I think it should be some wrapper for the native realization including fallback for earlier flash versions.

I like the idea of this, but is it fair to assume yet that people have flash player 11? Not sure what the penetration statistics are. And I am sure its more than when you submitted now, but perhaps there should be some fall back to previous library if that var doesn't exist.

I passed that the code replace like this:

JSON.encode(msg); -> com.adobe.serialization.json.JSON.encode(msg);
