* A bit more work on main window / document / commands stuff.  This is still
  pretty unstable.
* Enable CSV file reader also to read files with other separators (e.g. .lab
  files with space separators)
* Show "(R)" on waveform display when resampling during playback
* Add ability to import additional audio files (can't process them yet)
* Fixes to spectrogram cache for multiple views
* Fix to avoid floating-point exception in sparse model when resolution not
  set yet
