adminstream: fire disconnected event on lower layer disconnect This may in theory cause multiple disconnect events for the adminstream client, if the only code using that wasn't calling os.exit right away. Hence, this should be a good enough partial fix for #1671. It is not a full fix, because the shell will only notice the disconnect after one has hit enter in the input; until then, it is stuck in a read() call to stdin and completely oblivious to the disconnect.
