Use sys.executable to launch python scripts

[take-cheeze]

So that scripts like main.py is launched by same python executable used by configure.py

Hello @take-cheeze and thanks for the PR, were you able to test it on Linux and Windows?

[take-cheeze]

I've tested in macOS. Maybe windows may have some trouble so I'll test it

Seems creationflags=subprocess.DETACHED_PROCESS is required to open configure.py and main.py because with normal Popen process will be also closed with the parent process.
Though this feature is only for windows...

I tested your new changes on Windows, but now when I click on "Save and run" from the configuration window it starts the main.py script in a new terminal window, whereas previously it started the script in background.
Same thing when main.py is running on a tray icon right click > "Configure" it starts configure.py in a terminal, not in background.
Do you see the same behavior on your machine?

I'm running it from Terminal app so it seems to be the difference
