Fixes: #47

We want to be able to validate the appdata file even when building the
Flatpak bundle.

Move the description up top, and fix the link to the contribution
guidelines.

The build sandbox does not have a network connection, so the validation
cannot reach the screenshots.

We have to use `validate-relax` because the `validate` command is too
strict by default, and will choke on our captions and screenshot files.

We don't need it any more, and it's been dropped from GNOME.

We add a custom class, called "devhelp-hidden", that can be used by
tools generating the documentation to hide UI elements that should not
be visible when browsing the HTML in DevHelp.

We should allow modern API references to detect when running under
DevHelp, and update their style in ways that improve integration.

We should look for DevHelp books under XDG_DATA_DIRS/doc,
XDG_DATA_HOME/doc, and the Flatpak host /usr/share/doc directories. Not
every API reference is built with gtk-doc, or installed under the
DevHelp directory.

And add a manifest for the stable profile.

During the GNOME development cycle we want to visually distinguish the
development builds of Devhelp from the stable, system one. Additionally,
we want to be able to run the two builds at the same time.

Drop the "Quit" element: there is a "close" button right next to the
menu button.

Drop the single element section for the "Preferences" element, and
instead group it with the rest of the application-level actions.
