[Julian Sparber <jsparber src gnome org>]

    main_window: wrap room_info GtkBox in GtkScrolledWindow
    
    The room_info labels could cause the leaflet to fold before
    they could ellipsize, causing Fractal to fold at the wrong width. By wrapping in ScrolledWindow we work 
around that issue.
