PEP8 plugin Installation instructions for other editors

In https://github.com/pyvec/naucse.python.cz/pull/306, Lumír added initial instructions for installation of pep8 plugins for editors.

But the situation is not that simple. For Atom we now have simple step by step description and for other editors just a note about PEP8. But installation for Notepad++, Gedit and Kate requires a manual download of plugins and/or copying a script from various sources to right folders which may not exist on the filesystem etc.

• Notepad++ - https://kmonsoor.wordpress.com/2014/05/02/pep8_tonizer-on-for-notepad-make-your-python-code-pep8-compliant-on-editor/
• Gedit - https://github.com/khertan/gedit_flake8
• Kate - https://github.com/goinnn/Kate-plugins#id15

Question is whether it's a good idea to add the complicated guide for plugins installation to editors' pages when mentioned editors aren't used widely.

Revisa las instrucciones existentes de los editores y la guía inicial de instalación de pull request 306; después, compara las fuentes de los plugins de Notepad++, Gedit y Kate enlazadas aquí. Determina si estos pasos de instalación deben aparecer en las páginas de los editores y define un alcance coherente para cualquier adición.
