Keep the digital window's N1MM settings

The settings N1MM keeps for its digital interface: how many message buttons to
show, which of the two window scroll types to use, hover mode, the callsign
pause routines, what a callsign is checked against before it is highlighted,
which files that check reads, whether the grab list is cleared on a CQ or a
QSY, what happens to AFC and the mark tone on a run to S&P change, and whether
the receive pane is copied to a text file.
