  MythMusic: Improve Spectrum and Squares (#771)

* MythMusic: Improve Spectrum and Squares to work better.

By borrowing lessons learned from Spectrogram: process the whole
signal, use the same 16k FFT and MelScale, upgrade to 128 display
bars, separate left and right channels.  On the menu, Spectrum is
renamed to SpectrumBars and SpectrumDetail becomes then new Spectrum
to sit next to the related Spectrogram.

* MythMusic: better variable names in LogScale, MelScale
