In an object return message, send a null-terminated empty string in binary bucket to prevent a viewer 3 crash.
This is the message sent to the client when the object is returned. We were sending byte[0] in the binary bucket. This didn't kill viewer 1 but did terminate viewer 3 (don't know about viewer 2). So sending "\0" instead. This is to address http://opensimulator.org/mantis/view.php?id=5683
