Fixed a small mistake and re-wrapped the tarball, please re-fetch.

Right, forgot to make it optional, will do so.

I need to refresh my memory, will take a look.
Not enough compute cycles in a day :)

I'd also like to replace the use of Net::Server::Multiplex in
amavisd-signer by 0MQ - the async support in the Net::LDAP module
is very poor.

And modify p0f-analyzer.pl to work with the new version of p0f.
