Dynamic Rule Messages not being recorded correctly

[P-a-d-r-a-i-g]

When a rule_message is logged it uses the following SQL:

$sql_ruleMessage = 'INSERT IGNORE INTOrule_message(message_ruleId,message_ruleMsg) VALUES (:MessageRuleId2, :MessageMsg)';

So, the next time the same ruleId is used, it doesn't do anything but links to the existing rule and message. So, the 1st ruleMsg logged is the one that applies to that rule forever.

The problem with this is that some ruleMsg text changes per call, such as the inclusion of the source IP address e.g. Denial of Service (DoS) Attack Identified from x.x.x.x (y hits since last alert).

We can't do INSERT ... ON DUPLICATE KEY UPDATE because then the latest message will always be the one shown then.
