[Swfdec] AS context->global not an object problem

[Benjamin Otte]

Yeah, this is one of the places where something nonobvious happens.
SwfdecPlayer unsets the current global object unless it is actually
executing code. This is because multiple global objects can exist at
the same time due to the Flash security model (feel free to google it
up, I'm not gonna get into details).
The internal Swfdec code uses the functions
swfdec_sandbox_use()/swfdec_sandbox_unuse(), but they are not exported
as public API.
So I don't think there's any chance for a user of the public API to
modify the state of the Flash player currently. Certainly the
SwfdecAsContext APIs don't work.
