Was indeed a bit painful. Patch attached. Moved the gsmget code into the gadget,
removed all gsmget spawn and communication handling, split edje updates into
update_signal and update_operator, passing the instance around.

It works fine for me with FSO, but please test it with qtopia first to see if it
breaks something.

Good idea. Sadly it is a bit more difficult. FSO does not have a OperatorChanged
signal. That's inside StatusChanged. The latter brings you also some more
informations. I'll have a poke at it once this one is in.
