Separate kiosk mode from restrict mode
Restrict mode will focus on sandboxing, while kiosk will continue
to restrict IRC access through a public kiosk. Kiosk mode without
restrict mode allows execution of man 1 catgirl with /help, assuming
external sandboxing.

The /list and /part commands are also added to the list of disabled
commands in kiosk mode, since they are pointless without access to
/join.
