Documentation: Reformat documentation_contents.rst

Now that documentation_contents.rst serves as a navbar for the docs
pages on the website, reformat it to present the links in a more
logical order. The list is split into three sections for Users,
Developers and System Integrators, with a slight break between
each section and a header above the links.
