Doc updates
Some minor doc updates slated for 0.37.0:
* home: Fix link
* layout-manager: Fix doc string
This function is private that's no reason to trigger warnings.
* build: Add quick-setting-plugins to summary
* docs: Mention .phoshdebug
* docs: Link to more manpages
* docs: Enable fatal warnings during doc build
This makes sure we no longer ignore links that became stale or
are mistyped.
We start to fail on gi-docgen warnings to catch new ones fast. Let's see how well this works out.
