Review the list of editors

[aoloe]

#71 already brings an important issue: free software editors should come first.

on the other side the list did not age well:

• Thonny is probably nowadays the best way for starting with Python on Windows (it comes with all batteries included... and is small to download)
• Visual Studio Code is Free software and one of the editors of choices for professional programmers.
• PyCharm can also be considered as Free software, is all batteries included and of professional grade.
• Spyder, the default editor / editor in Anaconda.

On the other other side:

• Atom is disappearing: still worth to list it?
• Sublime is probably still a good editor, but I don't see why it should be on a list for beginners.
• Geany, TextMate, Gedit, Kate, Komodo should probably not be mentioned (never seen a beginner or a professional programmer using them. of course there are people using them, but they are not common tools for programmers.

Finally:

• It's probably worth to list Jupyter as a possible solution, for those with a data science background and who are in an environment where it is in common use (I would not suggest its use in a general text book, but it should probably be mentioned as a possible way to learn python)
