The Status(1) message acquires the new fields Frequency Tolerance, T/R
Period, and Configuration Name. The Rx DF, Tx DF fields become
unsigned (this should be a benign change which is just for correctness
as -ve values have never been possible).
The Close(6) message becomes bi-directional allowing external
applications to gracefully close down WSJT-X instances.
A new message SwitchConfiguration(14) is provided that allows an
external application to switch the current configuration of a WSJT-X
instance.
Another new message Configure(15) is provided to allow external
applications to adjust some key parameters like the mode and submode.
See the NetworkMessages.hpp header commentary for full details. The
UDPExamples/MessageAggregator reference application has been updated
to be able to exercise all of the above changes.
Note that this commit enforces stricter checking on the
"Settings->Reporting->Allow UDP requests" option, which must be
checked before any state changing incoming messages to a WSJT-X
instance are processed.
This change incorporates a reorganization of the GUI code with
widgets, validators, models, and item delegates being moved to
sub-directories.
Relax the requirements of the ForeignKeyDelegate and related
CandidateKeyFilter classes to allow them to work with constant model
pointers for both referenced and referencing models.
