Changes:

AUTO_UPDATES enabled for new installations in csf.conf
Removed the JS LF_EXPLOIT_CHECK as it is no longer prevalent. If still set in csf.conf it will be ignored
Check MESSENGER service to ensure privileges are dropped before starting the daemon
Drop privileges when peforming removal during LF_DIRWATCH_DISABLE
For new installations, IPV6 enabled if IP6TABLES exists and an IPv6 address is found in the output from IFCONFIG. IPV6_SPI is set according to the kernel version (i.e. whether SPI is supported or not)
