Server Bug fix: Make D-Bus introspection work again.

* mandos (DBusObjectWithObjectManager.Introspect): Bug fix; call
                                                   method Introspect,
                                                   not class
                                                   DBusObjectWithAnnotations.
  (alternate_dbus_interfaces/wrapper/fixscope): Make wrapped D-Bus
                                                signal function look
                                                like a D-Bus signal so
                                                Introspect can see it.

        If a client is compromised, its downtime should be duly noted
589
 
        by the server which would therefore disable the client.  But
590
 
        if the server was ever restarted, it would re-read its client
591
 
        list from its configuration file and again regard all clients
592
 
        therein as enabled, and hence eligible to receive their
593
 
        passwords.  Therefore, be careful when restarting servers if
594
 
        it is suspected that a client has, in fact, been compromised
595
 
        by parties who may now be running a fake Mandos client with
596
 
        the keys from the non-encrypted initial <acronym>RAM</acronym>
597
 
        image of the client host.  What should be done in that case
598
 
        (if restarting the server program really is necessary) is to
599
 
        stop the server program, edit the configuration file to omit
600
 
        any suspect clients, and restart the server program.
