    window-slot: Make back_or_forward() a slot method
    
    We define a NautilusWindow method in nauitlus-window-slot.c. That's
    just wrong.
    
    Also, there is no reason for this to be a NautilusWindow method,
    rather than a slot one.
    
    The only consumers are NautilusWindow and NautilusToolbar, and both
    have a pointer to the current slot, so let's make this a slot method.
    
    For convenience, also add a privade NautilusWindow wrapper method.
