log4j and additional log param

I didn't know that so easy you can add to logs for example http session id. You need only put into MDC object value and later set log pattern as %X{sessionId}.

When I did that I had to find good place to put into MDC my sessionId parameter. I created web filter to archive that. Filter is simple and should be executed in correct order in chain.

I have to admit I had problem with logging exception stack trace. I implemented ThrowableRenderer and have set throwableRenderer tag.
