Cannot raise UnsupportedMethod in DeferredResource

This is completely lame. Due to the way that exceptions are handled in a deferred and the fact that relies on receiving the UnsupportedMethod exception for flow control, makes it impossible to really effectively use the DeferredResource.

Using exceptions for flow control may be pythonic, but it's wrong in this case. Arguably, UnsupportedMethod isn't all that exceptional considering how much processing it does. Better would be to have render return a special error code if it can't find a method for the specified HTTP METHOD instead of raising an exception.

Run this command: twistd -n -l- -y ./test_deferred_resource.tac

And then send a PUT or POST or some other Unsupported Method to the server and you'll see what fun happens.

Yea, this is lame.

Removing from unrelated milestone, though.
