New csf v4.74

Changes:

• Removed FUSER from csf.conf as it is no longer used
• Added UNZIP to csf.conf which is required for Country Code to CIDR functions
• Modified the Country Code allow/deny/allow_filter feature to generate CC CIDRs from the Maxmind GeoLite Country database instead of using iplocationtools.com. Note: GeoLite is much more accurate that the previous zones used. This also means that there are usually more CIDRs for each CC which adds to the burden of using this feature
