[cactus] Configuration of logj4

[henrik . fredholm]

Hi

Thanks for a very usefull unit testing framework. 

It would be very helpfull if you could switch off or have a more
intelligient configuration of log4j. I'm using log4j in my components and
Cactus gets in my way becase Cactus reinitialises log4j and thus ruins the
original setup.

A solution could be to check if log4j has alreay been initialized by a
component outside the cactus framework or a configuration switch to disable
the use of log4j by Cactus.
