* Fix up and simplify the LayerTreeModel, removing a horrible memory leak
* Move phase-unwrapped frequency estimation from SpectrogramLayer to
  FFTDataServer
* Make the spectrum show peak phase-unwrapped frequencies as well (still
  needs work)
* Start adding piano keyboard horizontal scale to spectrum
* Debug output for id3 tags
