* Cleaning up and refactoring the OpenSoundNode code to use a single coding
  style and be less C-like in many places.
* Fixed quite a few memory leaks in OpenSoundNode.
* Removed large chunks of inactive code originating from the MultiAudioNode.
* Transfered some functionality into NodeInput and NodeOutput, could be more.
* No functional changes.
