mod_smacks_noerror: Add ability to silence errors if mod_offline is disabled

This will also silence "message not delivered" errors if mod_offline
is disabled and all clients are offline.
This assumes working MAM for all clients (lready assumed by the rest of this module).

 unacked message stanzas instead of sending error replies.
 Unacked iq stanzas are still answered with an error reply though.
 
+If you disable mod_offline, this module will also silence "message not delivered"
+error messages that will otherwise be generated when prosody would normally
+store offline message but can't do this because of disabled mod_offline.  
+If mod_offline is *not* disabled this module will not change offline storage
+behaviour at all.
