[gnome-shell/gbsneto/remove-generic-container: 45/56] layoutManager: Subclass GObject.Object

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

    layoutManager: Subclass GObject.Object
    
    LayoutManager is currently a pure JavaScript class that
    relies on the rudimentary Signals.addSignalMethods() to
    handle signals. This is an inefficient implementation of
    one of the most central classes in GNOME Shell.
    
    In addition to removing Shell.GenericContainer, then,
    turn LayoutManager into a proper GObject.Object subclass.
