Update index to include de version
Major reshuffle, reproduceable i18n

- Cleaned up folder structure. All normal source now just resides in
  source folder, all build files reside in _build.
- Configuration is now just in source/conf.py
- fabfile updated to allow for reproduceable and maintainable i18n.
- The translations in `source/_locales/de/LC_MESSAGES/` should be
  reworked into the proper files under the `source/locale/` folder.
- This is following the i18n practices given by
  http://sphinx-doc.org/latest/intl.html and
  https://pypi.python.org/pypi/sphinx-intl#quickstart-for-sphinx-translation
- Introductory index.html made slightly fancier!

Also, changing wording on prison slightly
Add a new section on the "programs needed".

We've seen this many times before - people can get
python, but don't know what to use to write it.
So I've added a section on good code editors to use.

They're specifically not IDEs.

This also allowed reorganising the last section of the
page to be more compact and easy to follow (less broken
up by the dialogue boxes)
