Rewrite "Install Plone from its packages" to be streamlined.

Remove duplicated or obsolete content, replacing duplicated content with links to source material.
Reorganize the remaining bits into a new supplementary page "Manage add-ons, packages, and processes".
Add Make and cookiecutter-plone-starter to the Glossary.
Remove now unused toggle style and JavaScript.
Optionally style images similar to figures, with <img class="figure" ... >
