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.
