Cannot launch apps in BlockEditor directly because exporting PYTHONPATH is required

[zdebanos]

Works fine for the GUI with pysim-run.sh as this script extracts the new PYTHONPATH.
However, I can't launch any other apps directly using $PYSUPSICTRL/BlockEditor/app.

The solution is to export PYTHONPATH by yourself, but I propose a more general script pysim-run.sh whose first argument shall the name of the application to be launched. This way I could launch qtgScope (for example) without putting PYTHONPATH in .bashrc (.zshrc).
