subsequent regenerations.

This means that "CQ DX", "CQ VT", etc., will be presistent until
changed back.

Fix some signoff issues with auto-sequencing

73 messages from other QSOs on  frequency should now be ignored rather
than being processed.

Also some  long overdue refactoring  and tidying of  non-idiomatic C++
code in the logbook directory.

Auto-Sequencing algorithm for DXpedition station:
Start:
CQMsg = "CQ VK9MA" (or "CQ UP VK9MA", "CQ 116 VK9MA", etc.)
TxMsg = CQMsg
Ntry = 0
QCALL = "" # Callsign of current QSO partner
go to Transmit
Transmit:
TX # (... takes 13.6 s)
go to Receive
Receive:
RX # (... takes ~14 s)
N = number of decodes # RxMsg[i], i=1,N
if(N == 0)
go to Transmit
J = index of a reply from current QCALL # RxMsg[J] = "VK9MA QCALL R<rpt>"
if(QCALL == "") # No QSO in progress
Select new QCALL # Op chooses a caller
if(QCALL == "")
TxMsg = CQMsg # No callers, we'll CQ again
else # QSO in progress
if(J >= 1) # Expected message was received
log the QSO with QCALL
QCALL = ""
Select new QCALL # Op chooses a new caller
if(QCALL != "")
TxMsg = "73 NOW QCALL <rpt>" # Start a new QSO
else
TxMsg = "73 " + CQMsg # No callers, we'll CQ again

Ntry = Ntry + 1 # Expected msg not received
