* Simplify maker names in plugin menu
* Make sure derived models have a name (based on the transform)
* Don't start deriving a model from a derived model until the derived model is
  ready
* Tidy up completion management in writable wave file model
* Make writable models save/reload correctly from session file (i.e.
  regenerating from the original transform)
* Same for dense 3d models -- don't save the data, just the transform details
* Add a comment describing the SV file format
