Review request for kdelibs and Olivier Goffart.


Summary
-------

Qt is not smart enough not to avoid loading a style that is already set. This avoids a unneeded creation and deletion of the current style for me. It works for all styles since QStyleFactory::create does
    if(ret)
        ret->setObjectName(style);

Testing
-------

Started an app, it worked, Oxygen destructor was not called like it was before


Thanks,
