Currently we have two kinds of user documentation: * the about page[1] which is written in HTML and part of the web application and can therefore link instance-specific pages (like e.g. the preferences) via Jinja variables * the Sphinx documentation[2] which is written in reStructuredText and cannot link instance-specific pages since it doesn't know which instance the user is using The plan is to integrate the user documentation currently in Sphinx into the application, so that it can also link instance specific pages. We also want to enable the user documentation to be translated. This commit implements the first step in this endeavor (see #722).
