[slf4j-dev] New Class

[Ralph Goers]

I added a new class to slf4j-ext. Should I create a bug to track it? I 
don't see the "normal" maven changes.xml either so I guess that isn't 
part of the process?

On a related note, the class I added has a dependency on commons-lang. I 
made it optional so that users of XLogger wouldn't be required to bring 
it in. However,
the Javaassist library isn't optional so it would be brought in under 
the same circumstances. Should that be optional also? Or should I just 
have let commons-lang
be required?
