New csf v4.87

Changes:

Ignore csf.rignore for LT_POP3D and LT_IMAPD
Removed unnecessary csf.locks during some GLOBAL list updates
Updated Copyright notice
Modified the block message for LF_MODSEC and LF_SUHOSIN to be more appropriate ( i.e. not “login failures” )
Added new block options for BIND denied requests: LF_BIND, LF_BIND_PERM, BIND_LOG. This works in the same way as the other similar blocks, e.g. LF_SUHOSIN. It will block IP addresses that have had BIND (named) requests denied more than LF_BIND times in LF_INTERVAL seconds. Currently named client denied log lines for “update” and “zone transfer” trigger the option
Modified GLOBAL_ routines to continue if retrieval for one fails instead of immediately exiting
Added IPv6 check to Server Check
Display DNS lookup results for IP addresses if CC_LOOKUPS is enabled on single line comments (lfd.log, csf.deny, etc)
Added new options LF_PERMBLOCK_ALERT and LF_NETBLOCK_ALERT so that the respective email alerts can be disabled
Updated IP::Country
