Georges Basile Stavracas Neto 158591a346 network: Replace the notebook with a stack 
The Network panel uses a GtkNotebook internally to manage
the different setup pages of the network devices. While it
does the job, we now have a modern widget for that: GtkStack.

With GtkStack, managing the pages becomes a lot easier and
we gain almost for free the nice transition between pages,
besides of course being a widget that consumes slightly less
resources.

Besides all these gains, using a GtkStack will allow us to
implement the new Wi-Fi panel in a more cohesive manner,
sharing large portions of code and avoiding copy pasta.

This commit then turns the GtkNotebook into a GtkStack, and
renames and adapts the code to reflect that. Fortunately,
the code got actually simpler with the move.
