[Lognorm] log classification with liblognorm

[David Lang]

First off, I have not used mmlognorm for anything other than seeing that it 
works, so take that into consideration :-)

However, as I'm looking at your rule, you have "mytag" outside of any matching, 
so it would be treated as a literal, just like "Denied ICMP" wouldn't it?

in your syslog template, try putting %$!number2% and see if it outputs the 
correct value. it looks to me like that variable is being set correctly.
