Changing ForwardMessageToExternalHost to postMessage and passing a proper

MessageEvent object to the onmessage handler.

Also adding support for origin and target parameters.  The origin parameter is
implicit but target can be specified when calling postMessage.  If no target
is specified we default to "*".

At the moment I'm only allowing target == "*" messages to pass through since
I haven't implemented support for matching more complicated patterns :)
