Method kBase::makeClass is calling ref_call_user_func_array no matter if he
has only class name or class name + constructor arguments passed. This slows
downs the things a little bit. I propose to use code, mentioned above, that
was called from kFactory class to optimize things.
if ( func_num_args() == 1 ) {
$class = new $real_class();
}
