Use webkit2gtk 4.1 instead of 4.0

See merge request !1

Closes: #1061462

This seems like a good idea in 2021^W almost 2022, and makes Element
considerably more responsive.

Fixes #96

Note: for backward compatibility, the name of the URL setting remains riot-url

 * This makes the Revolt window hide and show when the user clicks on the
   status icon. It matches the behavior of other applications with status
   icons like Gajim or Quassel.

   - If the application window its focused, when the status icon is clicked,
     then the application window its hidden (not simply minimized).
     The window geometry and coordinates are saved for restoring later.

   - If the application window its hidden, when the status icon is clicked,
     then the application window its restored and bring to the front.
     It also restores the previous saved window properties (if any).

   - If the application window its minimized or not focused, then it simply
     brings it to the front when the status icon is clicked.

* This adds a new setting "hide-on-window-close", disabled by default.
* If this setting is enabled, then when the window close button (X) is
pressed the window will hide instead of closing.
* This is useful for desktops with a tray bar and a status icon, where
the user is used to close the program by selecting the quit option from
the contextual menu of the status icon instead of by closing the window.
* The setting can be toggled with:

  gsettings set org.perezdecastro.Revolt:/org/perezdecastro/Revolt/ hide-on-window-close true

This needed adding intltool to the build, and asrranging to pass
-Wno-error when building libdbusmenu as it uses deprecated GLib
features which cause warnings.

Fixes #90

These are fixed and copied over to the theme directories, and they will
be always the same regardless of which application id is being used at
runtime.

This should fix the bug with the status icons from issue #58 and there
are good chances that this will help #87 and #83 as well.

This will show a menu bar when CSD is disabled, which is not great as it
mostly chews vertical screen real estate, but at least solves showing
the icon+menu when CSD is enabled and the GNOME Shell topbar is not
configured to show the application menus, or when running Revolt on a
DE which does not have some shell UI for the application menus.

Removes the go-back, go-forward, and stop actions from the context
menu of the web view, and adds items to open the Revolt preferences
and the Riot settings. The latter may come in handy in those cases
where the appmenu is not shown.

Fixes inability for Python to find the WebKit2 API.

This allows to automatically install the runtime's repository and the
runtime when installing Revolt from the flatpakref.

This allows for the icons to be exported by Flatpak. Which in turns
should fix the missing status icons for GtkStatusIcon (see issue #58).

This allows easily building i386 versions of the package as well, by
just doing:

  % ./make-flatpak.sh --arch=i386

(Of course, this needs the corresponding Flatpak runtimes installed.)
