Change security level 0 to be more forgiving

changed from 0 to 1:
 timeperday
 timepercall
 callsperday
 postsperday
 emailperday

There are restrictions to remove access to these features if that's what the
sysop desires.

This will allow unauthenticated mail clients to post a single message (per day)
to a sub-board, when there's a posting alias set up (sub:* in alias.cfg).
