b4abedca61 Simplify equalization logic - still need to fix & vs ^ display.

bf364de0af First attempt at a UI phase compensation tool for MSK144 
This builds on the static phase compensation in the MSK144 decoder and
the phase  analysis and  polynomial fitting  capabilities also  in teh
MSK144 decoder,  by allowing  captured data to  be selected  for phase
equalization from the WSJT-X UI.

Reads  captured phase  compensation  curve  estimate files  containing
fitted  polynomial coefficients  and measured  phase data  from MSK144
receptions. Intent  is to select a  compensation curve that is  from a
known transmitter like  an SDR which have good  phase linearity. Phase
plots and compensation polynomials may be viewed and compared with the
current compensation polynomial. A  suitable polynomial can be applied
to be use in all further decoding of MSK144 signals.

Plots of  the currently  selected polynomial  and its  modified higher
order terms  polynomial which is  actually used in  equalization (this
plot may  be dropped - it  is just for  kicks at the moment).   When a
captured phase analysis file is loaded plots of the measured phase and
the proposed best fit polynomial are shown.

Basic  maintenance  is also  included  allowing  clearing and  loading
captured  plots and  an option  to revert  to a  flat no  equalization
curve.

More to come on this as  amplitude equalization is also possible, this
will probably  be similar, maybe even  plotted on the same  graph with
dual  axes  for phase  and  amplitude.   Amplitude correction  from  a
measured  reference   spectrum  could  be  viewed   and  selected  for
equalization for all modes. TBC...

This   change    also   introduces    the   QCustomPlot    3rd   party
widget. Currently this  is statically linked from a  qcp library built
by the WSJT-X CMake script. This will probably be migrated to a shared
object (DLL) build as a CMake external project, once some CMake script
re-factoring  has been  completed,  which  is more  in  line with  the
QCustomPlot author's  intentions. This  will allow efficient  reuse in
other tools shipped with WSJT-X.

e58ccdfd76 Temporarily disable the Tx/Rx transient suppressor introduced in r7424 
This code was causing the JT9 decoder  to fail to decode, maybe due to
high  noise  levels  and  the resulting  discontinuity  introduced  by
zeroing out samples.

JT65 VHF modes and color-highlights the Tx message box.
