Fix iPython View
In an attempt to fix iPython functionalities of Gajim, I applied the patch used in the Accerciser project: https://gitlab.gnome.org/GNOME/accerciser/commit/3008be6e0cbf6d42b55354405b37693b5c4c62c6
I also took the opportunity to take some other portions of the code used by Accerciser to avoid further tracebacks. I added a check for IPython in
gui_interface.py , so we can abort early if IPython is not installed. Additionally, some code-cleanup was done.
Installed iPython version: 7.5.0
Usage is described here: https://dev.gajim.org/gajim/gajim/wikis/development/IPythonEmbeddedShell
