Experimental new behavior for "Lock Tx=Rx" and for clicking on waterfall and decoded text.

1. Checkbox "Lock Tx=Rx" is now labeled "Lock Tx Freq", and its meaning is
quite different.  If checked, the audio Tx frequency cannot be changed.
It's like the "Lock" function on some transceivers.

2. Clicking on the Wide Graph waterfall and on lines of decoded text now
behave as follows:

Click on       Action
---------------------------------------------------------------------
Waterfall:     Click to set Rx frequency
               Shift-click to set Tx frequency
               Ctrl-click to set Rx and Tx frequencies
               If Lock Tx Freq is checked, Tx freq does not move
               Double-click to set Rx frequency and decode there

Decoded Text:  Double-click to copy transmitting callsign to DX Call
               and locator to DX Grid; change Rx frequency to decoded
               signal's frequency; generate standard messages.
               Tx frequency is not changed unless Ctrl is held down
               and Lock Tx Freq not checked.

If this experimental behavior is adopted, some descriptions in the
User Guide and Special Mouse Commands will need to be updated.

3. Starting to implement a new function on the Tools menu,
"Solve for calibration parameters".  This is not yet finished;
DO NOT USE in its present form.

Another try at optimizing the GUI for simplex and split behavior.  Details below:

1. Checkbox "Double-click on call sets Tx and Rx freqs" has been removed
from the Settings -> General tab.

2. Checkbox "Lock Tx Freq" on main window is relabled "Hold Tx Freq".

3. Behavior now defaults to the "simplex" behavior in use up to code
revision r8123.  In particular, double-clicking on decoded mesages
that do not contain your own call moves both Rx and Tx frequencies.
If the first callsign is your own call, only Rx freq moves.

4. If "Hold Tx Freq" is checked, double-clicking on decoded messages
moves the Rx frequency; Tx frequency is moved only if CTRL was held
down.

5. Clicking on the waterfall moves Rx and Tx frequencies as before:
Rx only on a simple click, Tx only on SHIFT-click, and both on
CTRL-click.  This happens even if "Hold Tx Freq" is checked (which
is why this box is no longer labeled "Lock Tx Freq").

Improved frequency calibration

Measure check  box added to FreqCal  mode, check to record  to fmt.all
with  current  calibration correction  disabled,  uncheck  to see  the
impact of the current calibration parameters.

The  fmt.all  file  is  now  optionally  renamed  to  fmt.bak  when  a
calibration solution  is accepted.  This allows  users to  preserve an
fmt.all file that they might have edited for best fit.

A calibration procedure might proceed thus:-

1) select FreqCal mode,

2) step through suggested  calibration test frequencies deleting those
that have no usable signal,

3) enable "Menu->Tools->Execute frequency calibration cycle" and check
that suitable signals are present,

4) select a suitable FTol and T/R period,

5) check  "Measure" and let the  cycle complete a few  times to gather
data,

6) uncheck "Measure" to complete the data capture, optionally tidy the
fmt.all file with your favourite editor,

7) push "Menu->Tools->Solve for  calibration parameters" and accept if
you like what you see,

8) sit back and admire your accurately frequency calibrated station.
