Title: Search direction

I've completed adding the SearchDirection class to Pylearn2 and I tested it. It seems to work as I intended.

I also added some subclasses (adagrad and momentum, or at least momentum in the way I understand it) to test it a little.

If everything is okay with my pull request, I think there would be some cleanup to do in the SGD class as some of the hacks added over time might be replaced by a SearchDirection subclass.
