Matthias Clasen 92662828ba messagedialog: Respect the gtk-keynav-use-caret setting 
We used to always make the labels in message dialogs selectable,
which is a bit problematic wrt. to keynav - the label can
unexpectedly 'turn blue', which irritates some people.

With the new gtk-keynav-use-caret setting, we can now only
make the labels selectable when it is required for accessibilty
reasons.

* SECTION:gtkmessagedialog
* @Short_description: A convenient message window
* @Title: GtkMessageDialog
* @See_also:#GtkDialog
*
* #GtkMessageDialog presents a dialog with some message text. It’s simply a
* convenience widget; you could construct the equivalent of #GtkMessageDialog
* from #GtkDialog without too much effort, but #GtkMessageDialog saves typing.
*
* One difference from #GtkDialog is that #GtkMessageDialog sets the
* #GtkWindow:skip-taskbar-hint property to %TRUE, so that the dialog is hidden
* from the taskbar by default.
*
* The easiest way to do a modal message dialog is to use gtk_dialog_run(), though
* you can also pass in the %GTK_DIALOG_MODAL flag, gtk_dialog_run() automatically
* makes the dialog modal and waits for the user to respond to it. gtk_dialog_run()
* returns when any dialog button is clicked.
*
* An example for using a modal dialog:
* |[<!-- language="C" -->
* GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT;
* dialog = gtk_message_dialog_new (parent_window,
* flags,
* GTK_MESSAGE_ERROR,
* GTK_BUTTONS_CLOSE,
* "Error reading “%s”: %s",
* filename,
* g_strerror (errno));
* gtk_dialog_run (GTK_DIALOG (dialog));
* gtk_widget_destroy (dialog);
* ]|
*
* You might do a non-modal #GtkMessageDialog as follows:
*
* An example for a non-modal dialog:
* |[<!-- language="C" -->
* GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT;
* dialog = gtk_message_dialog_new (parent_window,
* flags,
* GTK_MESSAGE_ERROR,
* GTK_BUTTONS_CLOSE,
* "Error reading “%s”: %s",
* filename,
* g_strerror (errno));
*
* // Destroy the dialog when the user responds to it
* // (e.g. clicks a button)
*
* g_signal_connect_swapped (dialog, "response",
* G_CALLBACK (gtk_widget_destroy),
* dialog);
* ]|
*
* # GtkMessageDialog as GtkBuildable
*
* The GtkMessageDialog implementation of the GtkBuildable interface exposes
* the message area as an internal child with the name “message_area”.
