Hi Ceki.

I have spent quite some time figuring out how to handle logging with 
object parameters with rogue toString() implementations and have found 
it too hard for me to get right in code, so I have delegated it to the 
developer using it to exclude these classes from the logging 
configuration (cheap, but works) by saying so in the documentation.

I also found a solution to this problem.  Basically it is "only 
instrument a class if the slf4j API classes are available to it" - that 
has turned out to work well for my real-life situations.

Also it is now robust against objects throwing exceptions when being 
toString'ed, as well as being able to show nested arrays of both objects 
and primitives.

It has taken quite some time but I finally now has this in a state where 
it will work with the multi-threaded real-life legacy applications I 
have at work, so unless you hear otherwise I would like to have it 
announced in the next release of slf4j.

I would appreciate your help in getting the jar file names right in the 
created manifest when you have the time.  I currently hard code them but 
it would be very nice if they could be extracted from the dependencies 
section.
