Updates to Users Guide.

Double-click on waterfall sets Tol to a reduced (mode-dependent) value.
Tol is saved/restored on program restart.
Added digital gain slider for setting input level.
Garbage decode "15P6715P67WCV" is rejected.
Arrays ss and c0 are copied and saved when newdat=1.  Further processing is
done on the copies.
