netinfo: allow setting an outbound-only peer list

Browse source 
by passing an additional argument of "outonly" or "o".

This has been requested in order to keep the output within screen limits when running -netinfo
as a live dashboard, i.e. with `watch`.

Also allow passing "h" in addition to "help" to see the help documentation.
