Note that FST4 QSOs are logged with MODE=MFSK and SUBMODE=FST4. The
new bands 8m and 5m are recognized. The ADIF header is expanded with
program and time stamp information.
This is a check box option in "Settings->Colors" rather than new
highlighting types so un-worked field highlighting and un-worked grid
square highlighting are mutually exclusive. The check box state can be
changed at any time, no log rescanning is necessary, and subsequent
decoded message highlighting will be according to the check box state.
Some logging applications export the BAND ADIF field with uppercase
characters. This change makes sure that the internal worked before
lookup indexes use uppercase throughout when fields that can come from
external sources are stored.
Settings option to highlight not worked before entities/grids/calls by
mode. Fix issues with highlighting decodes and generally refactor the
internal workings of ADIF and QSO recording for worked before
detection.
