New csf v2.87

Changes:

• Fixed duplication of settings during generic configuration upgrade procedure
• Only display version confirmation update message when running csf -u interactively (Thanks to Brian Coogan for the perl tip)
• Fixed issue with temporary files not being truncated before being written to, which caused problems e.g. with global allow/deny files
• Added new option CT_SKIP_TIME_WAIT to exclude TIME_WAIT state from connection tracking
• Updated the csf webmin module to use the &ReadParse() routine to overcome problems when running through SSL (Thanks to Tim Ballantine for this tip)
