added AppImage via pkg2appimage

* Docker turned out to be impractical since you cannot connect a dockerized Jack client
  to a Jack server on the host as library versions would have to match exactly.
  Neither did I get Netjack to run in Docker.
  Also when running in Docker, it would be tricky to get gnuplot to work (and Tcl/Tk support in the future).
  Especially the Jupyter notebook packaging would have been a lot easier, though with Docker.
* AppImage will automatically avoid bundling libjack and require a compatible libjack on the host instead.
* Using pkg2appimage ensures we can pull in dependencies as Debian packages.
* This version of AppImage.yml does not contain Jupyter notebooks.
