* Add FFT data server class to provide a file cache mapping for each
  required set of FFT parameters and source model. Make use of it in
  feature extraction plugin transform, though not in other places yet.

* Add zero-pad option to spectrogram layer and remove window shape option
  from the property box.  To be revised.
