A GUI-only setting says so on a terminal, and DumpDir reads back its directory

`Lift on` over ctl on a terminal answered "unknown control message" while
Config listed Lift as unsupported, and the ctl's DumpDir line read bare while
Config showed the path in effect. A setting word this frontend lacks is now
refused as `Lift is GUI-only` (GripWidth too), and DumpDir reads back the
directory in effect, as Config does.
