Ffgo

[FEATURE] Update the Polish translation. (PlayeRom Roman Ludwicki)
[MAINT] Update documentation and config_* files (oldish info, links).
(PlayeRom Roman Ludwicki and Florent Rougon)
[MAINT] Packaging fixes. (Florent Rougon)

[USABILITY] Update and improve docs/INSTALL/INSTALL_en. (Florent Rougon)

[MAINT] Change protocol from HTTP to HTTPS for METAR reports retrieval.
tgftp.nws.noaa.gov doesn't offer METAR reports over HTTP anymore.
This was still working for FFGo because the connection was
automatically upgraded to https. Now, we connect directly using
https when retrieving METAR info. (Florent Rougon)
[MAINT] Cheap optimizations in the generic code for aircraft and airport
lists. (Florent Rougon)
[BUGFIX] Fix crash due to incompatible changes in Ttk from Python 3.8. See
<https://github.com/frougon/FFGo/issues/2> for details. Thanks to
pav-rez for reporting this issue and providing patches.
(Florent Rougon)
[BUGFIX] Fix ugly 'Run FG' behavior when the selected airport or aircraft is
invalid (this used to print a half-baked error message that wasn't
designed for end-users). Thanks to pav-rez for reporting it (in the
same issue as above: <https://github.com/frougon/FFGo/issues/2>).
(Florent Rougon)
[MAINT] Change the default airport to BIKF. Keflavík International Airport
(BIKF) is currently the default airport in FlightGear. It is not
important for us to follow it, but doesn't hurt. (Florent Rougon)
[FEATURE] Update the French and German translations. (Florent Rougon and
chris_blues)
[MAINT] Update old URLs (mainly, change http ones to https when possible).
(Florent Rougon)
[MAINT/FEATURE] Refresh the setup.py script (Python packaging). FFGo is now
available in wheel format
(see <https://www.python.org/dev/peps/pep-0427/> for the
specification of this Python packaging format). (Florent Rougon)
[SECURITY] In README.rst, which yields <https://pypi.org/project/FFGo/>,
explain how to fetch my OpenPGP key over https and where to find
FFGo official tarballs available over https too. (Florent Rougon)

[USABILITY] Fix a mistake in the German translation. (chris_blues)

[USABILITY] Minor update to the default config regarding real weather fetching
(only the comment is changed). (Florent Rougon)
[USABILITY] Update the German translation. (chris_blues)

[BUGFIX] Pass --disable-terrasync when automatic scenery download is
disabled. Omitting --enable-terrasync is not enough, FlightGear
remembers the setting! (Florent Rougon)
[FEATURE] Add a configuration parameter and check box in the main window to
enable or disable automatic download of weather data (also known as
“real weather fetch”). This is convenient when one repeatedly runs
FlightGear to debug something and wants it to start as quickly as
possible. (Florent Rougon)
[USABILITY] Small layout adjustments in FFGo's main window. (Florent Rougon)
[USABILITY] Rewording of the MSAA tooltip: it doesn't seem to impact frame
rate that badly. (Florent Rougon)
