Automatically unwrap args in a MessageEvent, like we do in other events.

The way this all works is: when you send a primitive to the server, you
must wrap it up yourself, because there's no way for flash to distinguish
between the integer 3 and the floating point value 3.0.
But when it comes from the server, it's all wrapped up in a very specific
type and we can easily unwrap it.
