New csf v6.42

Changes:

• New BETA option RESTRICT_SYSLOG_GROUP. This has been added for a new RESTRICT_SYSLOG option “3” which restricts write access to the syslog/rsyslog unix socket(s). See csf.conf and the new file /etc/csf/csf.syslogusers for more information
• Those running our MailScanner implementation, you must be running at least ConfigServer MailScanner Script v2.91 for logging to work with RESTRICT_SYSLOG_GROUP
• csf UI option added for editing csf.syslogusers
• Fixed a bug in PT_LOAD not producing PS output
