Messages now have a direciton (in, out or none). Filters can this direction Outbound messages are no longer type 'admin' but are of the appropriate message type (i.e. 'zephyr') and are direction 'out'. Smartnarrow now works on outgoing messages 'info' updated to show more information for admin and outgoing messages Renamed pretty_sender to short_zuser and renamed long_sender to long_zuser
