[WriteLog] RTTY decode window

[Jon Suehiro]

I did not notice before.  But during WW RTTY contest, I realized the left
side in the Rittyrite window, there is the gray scale bar.  Once active call
is clicked into the Log CALL area, then the color changes to green scale,
and the line next to the brightest green is the current.  Once QSO is made,
then the color bar changed back to gray scale.  Very useful feature.  Jon
