[SabreAMF] String references serializing AMF3

[Evert | Rooftop]

Update: there doesn't seem to be a way to check if 2 scalar variables 
reference the same data. So I would say, don't implement this.. Could be 
a really bad idea.

For objects it is possible (and should probably be done), because you 
can do a simple == check.

I'll implement that one of these days.. Along with the fixes you 
provided I'll put out a 0.5..

To the other people on this list: if you got a feature request, be sure 
to let me know.. I'll create a roadmap for 1.0 soon, so people know what 
they can expect.
