* Add TextModel and TextLayer types
* Make View refresh work better when editing a model (previously edits might
  not be refreshed if their visible changed area extended beyond the strict
  frame range that was being modified in the model)
* Add phase-adjusted instantaneous frequency display to spectrogram layer
  (still a work in progress)
* Pull maths aliases out into a separate header in dsp/maths so MathUtilities
  can be included without introducing them
