Drop Qt4 and support Qt6

[txtsd]

Qt4 has been EOL since 2015.

It's time to drop support in the codebase, turn Qt5 into legacy, and focus on supporting Qt6 instead.

i was working on this on my fork here, if anyone could contribute that would help speeding up the process

[txtsd]

Oh good. I'll test it later today or tomorrow and see how I can help.

thanks!
the state of that fork is mostly working; it starts, renders the lists (though without the colored bars) and images, also updating the lists locally and remotely works fine.

there are still some issues with writing to files (especially the config one), but that is something I'm unable to work out how to fix.

@alsoGAMER How are you launching it? trackma-qt -6 does not do anything different, and it seems to be using qt5 like normal.

[alsoGAMER]

@txtsd make sure your local clone isn't broken, i made some big changes to the repo some days ago.

also I'm using an archlinux distrobox to run it with qt6 and it works flawlessly, so you can try that.

[alsoGAMER]

@txtsd did you get it working?

[txtsd]

Not yet. I've been battling respiratory illnesses :(

Oh i see, hope you'll recover soon.

TEST FAILED: /tmp/trackma/lib/python3.10/site-packages does NOT support .pth files
bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not
on PYTHONPATH and which Python does not read ".pth" files from.  The
installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /tmp/trackma/lib/python3.10/site-packages

and your PYTHONPATH environment variable currently contains:

    ''

Here are some of your options for correcting the problem:

* You can choose a different installation directory, i.e., one that is
  on PYTHONPATH or supports .pth files

* You can add the installation directory to the PYTHONPATH environment
  variable.  (It must then also be on PYTHONPATH whenever you run
  Python and want to use the package(s) you are installing.)

* You can set up the installation directory to support ".pth" files by
  using one of the approaches described here:

Please make the appropriate changes for your system and try again.

It doesn't show or recognize the -6 flag. Your qt6-rework branch is checked out.

[alsoGAMER]

I don't know why is behaving that way, i just retried the setup from scratch and worked perfectly fine.

Rebased @alsoGAMER's patch to get rid of PyQt5 from the system: trackma_qt6-rework.zip
For some reason github craps itself on unzipped patch-file.
