Version 3.23.08 - Changes from 3.23.07

NAVTEX update

* low pass mark & space individually 
* Use ATC and fft-filters adapted from RTTY modem 
* Correct display metric 
* Widen afc filter for 'jump 90 Hz' code 
* Use exact bit length 
* Calculated sync modification 
* see src/navtex/navtex.cxx for design analysis

Save Logbook

* Change system dialog invoked when saving logbook to 
  system save-as vice save.

Analysis mode

* Restore <CSV:on, <CSV:off, <CSV:t(oggle)

flrig PTT

* All user to select whether flrig PTT change triggers 
  RX/TX change in modem stata

flrig waiting

* Changed event recording level for 
  "Waiting for flrig" from INFO to VERBOSE

COM port close

* change effects the Windows COM port close process 
  - rigCAT startup process no longer dependent on order, xcvr 
    can be started before or after fldigi is running.  Tested 
    by Haris, SV1GRB.

Mac Logger

* Added UDP interface to read data exported by MacLogger 
  - UDP data stream on socket 255.255.255.255 / 9932 
  - User configurable items: 
    . enable/disable UDP socket reads 
    . Capture and use UDP Radio Report data 
    . Capture and use UDP Spot Tune data 
    . Capture and use UDP Spot Report data 
    . Capture and use UDP Log Report data 
    . Capture and use UDP Lookup Report data 
    . Enable UDP string capture to file 
      file in fldigi files/temp folder 
      filename: maclogger_udp_strings.txt 
* Added <signal.h> to threads.h to avoid missing reference 
  to sigemptyset in some gcc installs

fsq repeat last

* test for empty list of previous command

GCC 6 build

* GCC 6 defaults to -std=gnu++14, and attempting to build fldigi fails 
  with a number of errors. One is that C++11 added std::next and so 
  because of the "using namespace std" in src/fsq/fsq.cxx the global 
  variable 'next' and std::next are ambiguous. That can be easily solved 
  by qualifying ::next or adding using ::next at function scope. 
* The other errors are due to the different return type for 
  std::complex<T>::real() and std::complex<T>::imag() in C++11 and 
  later.

CALL capture

* add copy call to clipboard when capturing from Rx text

Scope View

* Corrected saved position/size status values

RigCAT modifications

* Separated no xcvr functions from rigcat loop operation 
* Corrected hamlib start/stop process to prevent 
  lockup when xcvr is not responding to CAT commands 
  - hamlib still creates a zombie process when trying to access 
    a bogus serial interface such as a bell modem 
* Added string / hex data LOG view 
  <LOGSTR>true/false</LOGSTR> 
* Added variable loop timing 
  <POLLINT>100...20000</POLLINT> 
  default 100 msec 
* Corrected use of BW-REPLY and MODE-REPLY in xml def file 
* Added ability to read and display Smeter and Pwr meter 
* Added debugging statements to exit functions 
* Fixed aberrant save frequencies2.txt file behavior 
* Added manual notch read/write using waterfall 
  notch filter interface 
* Added power level control for xcvrs with that CAT command 
  - set power level also used for logging 
* Updated tutorial on transceiver xml definition file structure. 
* Added <VERBOSE>bool</VERBOSE> specifier 
  - use during development of an xml file
