Title: GBRT API consistency

This is a cerry-pick of #1036 that addresses #1085 and some other API issues of the GBRT module.

Summary:

* Better docstrings
* ``GradientBoostingClassifier`` now has ``staged_decision_function``, ``staged_predict_proba``, and ``staged_predict``

These methods are important for efficient model selection for GBRT models.
