[virt-tools-list] [PATCH 03/22] app: simplify toggling visibility

[marcandre.lureau at redhat.com]

From: Marc-André Lureau <marcandre.lureau at redhat.com>

There is a hack to maintain the the toggle state to a desired state
within the "toggled" handler. (since there is no way to hook a signal
handler on "clicked" before "toggled" is emitted and handled by Gtk,
to avoid the recursion)

However it is only necessary for the ask-quit case. In this case, we
want to maintain the item active, which is simpler to handle than the
general case. Simplify the code by folding
virt_viewer_app_window_set_visible() and removing the static
"reentering" hack, only maintaining "active" on the last item.
