Bill Somerville f200506571 Add mode dependent working frequencies
Working frequencies are mode dependent  and a reset to defaults button
has been added.

Also re-factored much of the model  and item delegate code to simplify
several  of the  model  implementations. Introduced  a single  routine
called from main to register the custom types with Qt.
