Vincent Penquerc'h ae3ba53391 playsink: handle after-the-fact changes in converters/volume booleans
The playsink was nastily poking a boolean in the structure.
Make those booleans properties, so we are told when they change,
and rebuild the conversion bin when they do.

Some cleanup to go with it too.
