wav2sketch - Update for T4.x

Update effect_rectifier.cpp

Bug: was overwriting a read-only buffer

Minor gui text updates

Replace the text formula with a png graphic generated from some
LaTeX source.
Formulas in HTML apparently never made it in the mainstream,
and the recommendation is to use LaTex to generate images. See:
https://www.w3.org/MarkUp/HTMLPlus/htmlplus_45.html

To convert the .tex to a png, try:
  pdflatex formulas.tex
  convert -density 300 formulas.pdf -quality 95 formulas.png

Note in the GUI help text that the ToneDetect uses the
Goertzel algorithm.
