New csf v1.53

A new version of csf. I’m going to take a development break for a while, though any problems with the scripts/firewall will be worked on immediately. The new features:

• Optimised logging in lfd
• Improved error handling and reporting in lfd
• Modified WHM UI report to include all data, not just a single day
• Improved DROP logging to SYSLOG
• Added logging of dropped ICMP connections
• Added new option DROP_IP_LOGGING to log IP addresses that have been blocked in csf.deny or by lfd with temporary connection tracking blocks
