#5 run-reports.sh patch

[Mark Nagel]

The run-reports.sh script does not obey the username
information in nmis.conf -- this patch fixes that. I
am a bit concerned that 'id -gn' is not portable
enough. If that is the case, it may be better to
simply rewrite this as Perl. My patch also has a
simplification on the "day" case statement and added
exit statements for parameter errors.

NOTE - there is a bug in my patch! The initial assignment
of the username and groupname should use the ':-' operator
and not the '-' operator (e.g., should look like
username=${username:-nmis}).
