    EMailBrowser: Fix packing of preview pane.
    
    Using gtk_box_new() instead of gtk_vbox_new() changes the way child
    widgets are packed by default via gtk_container_add().  gtk_vbox_new()
    expands them by default, gtk_box_new() does not, and the preview pane
    was being packed with gtk_container_add().
    
    Packing widgets into a GtkBox with gtk_container_add() is usually the
    wrong way.  Use gtk_box_pack_start() instead, with expand=TRUE.
