[Fpga-synth] Digital Waveguide Monosynth

At the bottom of the article, I've added a zip file with the Verilog source
for a monosynth based on my digital waveguide experiments.  I found several
bugs in my code which I've fixed.  I also enhanced the project for use as a
monosynth.  The synth has switch selectable excitation of rectangular or
saw pulse.  The filter interface has been modified to "linearize" it's
response depending on whether you are doing strings or drums.  In either
case, the algorithm tends cause the entire keyboard range to generally
sound the same with respect to timbre.  Without this, it was possible to
set the filter such that at the low end, you got strings, but at the upper
end, you got drums.
