Title: Supervised CrossEntropy cost correction and new classifier layer

I think the pylearn2.costs.supervised_cost.CrossEntropy has an error in it and I have corrected it.

I also added a class in pylearn2.classification representing a layer which can be seen as computing the discrete cumulative distribution function for an ordered set of classes. Yoshua asked me to experiment with it.
