Rename the app-id to org.gnome.Settings since this is what
we've been calling it for many years now. Adjust all files
that derive from the app-id, such as the desktop file, D-Bus
service file names, search providers, GSettings schemas, to
match that.
Closes https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/344
- Move more code into the .ui file
- Don't save the dialog between runs - it's cheap to generate on demand
- Hold references on data passed to dialog
- Connect signals in "swapped" form
- Use standard naming format for signal callbacks
The row widgets are not full GtkWidgets. This means they are harder
to understand, use g_object_set_data which looses type safety and
cause the one .c file to be overly large.
Update this code to use a CcInputRow widget that uses GTK+ best
practice.
