Since 9d612ff1c7 this is required,
otherwise we never set up the GtkAdjustment and so the scales don't
display any values or widget to make adjustments, meaning they can't be
used.
Also call `notify_volume_cb()` from `update_ranges()` to initialise the
adjustment, since when we set the mixer control we now might not have
set the value.

Some devices have panels with a native resolution in portrait mode. In
these cases the monitor will likely be used in landscape mode.
Accept the modes as if they are landscape rather than portrait. A
further improvement would be to restrict the orientation setting.
Fixes#639
The previous code would make that browser the default handler for all mime types
it supported. This meant Firefox would become the handler for PNG and JPEG images.
Fixes#473
When the panel list is folded, either the panel items list or the
panel itself is shown, not both. And when the list is shown it
doesn’t mean anything for an item to be marked as selected.
Username policies differ across the distributions. See the discussion on:

It is not possible to hard-code some rules here without the need for
downstream modifications. Let's check the validity of usernames dynamically
over "usermod" to prevent this.
Just be careful that this is based on undocumented usermod behavior, which
may change in the future.
Tracker GSettings were previously stored in a global variable. This
seems to have been done to avoid difficulty passing the settings via
callbacks. Global variables are easy to leak and make mistakes with.
Update the code to have better callback handling so the variable can
be stored inside the object.
