* Add Thumbwheel widget for all our zooming needs
* Use QSettings to save/restore window size and position -- precursor to
  switching our preferences to QSettings as well -- wish I'd noticed it sooner
* Only suspend writes (not reads from the underlying cache objects) from the
  fft caches when repainting the spectrogram -- performance should now be
  significantly better
