According to the latest mockups for the connection editor dialog [1],
the IPv4 and IPv6 pages are supposed to use a table-like editor to
manage the routes. This editor is not only easier to comprehend, but
also improves the size of the dialog, requiring much less vertical
space to present the routes.
The current implementation, however, uses a vertical layout and a toolbar,
which is inefficient in its usage of space.
Fix that by implementing the table-like editor widget, both in IPv4
and IPv6 pages.
