[nautilus-actions] NAIDuplicable: are_equal, is valid default to TRUE

[Pierre Wieser <pwieser src gnome org>]

commit 3ca2b4f7cfd24a3d8d05db16baf90e6051960acc
Author: Pierre Wieser <pwieser trychlos org>
Date:   Mon Feb 21 19:44:50 2011 +0100

    NAIDuplicable: are_equal, is valid default to TRUE
    
    Rationale: if the implementation has not taken care of implementing the corresponding interfaces,
    then it is probably because this does not make sense in the given context. There is so no reason
    to suppose anything other here.
