New csf v5.11

Changes:

• Removed erroneous Port Knocking messages in lfd.log when PORTKNOCKING_ALERT not enabled
• Added ‘exe:/usr/bin/postgres’ to the cPanel csf.pignore for new installations
• Added retry timeout in WHM UI for checking www.configserver.com for new version information (to avoid repeated hangs when unreachable)
• Fixed LF_PERMBLOCK issue that flushed all temporary IP blocks, not just the IP being permanently blocked
• Added check to PHP Server Check that php -i output is complete
