Subject: AppImage: fixed Jupyter and ILua modes on all but my own system

* We cannot use the Pip-installed launchers since they have hardcoded paths.
  Instead we reference python3 explicitly in the /usr/bin/applause launcher.
* For some strange reason, the site-packages directory where all of the relevant packages are put
  is not in sys.path. So also export it via $PYTHONPATH.
