TCP based scan detection rules rewritten, they now inspect TCP packet window sizes, flags and/or MSS values in addition to just timing intervals and ports. This resolved almost all false positive alerts from trying to detect slower TCP scans, and also lowered detected Nmap scan speeds (including TCP types) down to speed -T1. Currently -T0 is still too slow to detect without false positives. Also, UDP and fragmented scan timing intervals were made more common between other similar rules. These latest rule fixes were based on WireShark captures gotten during recent rule testing. General cleanups. Cosmetic touches.
