Support for XGBoost PMML models

You can now import and export XGBoost PMML models. In PMML, an XGBoost model is an ensemble of TreeModels called a multiple model.

New probability_normalization parameter for PREDICT_XGB_CLASSIFIER and PREDICT_XGB_CLASSIFIER_CLASSES

Previously, the PREDICT_XGB_CLASSIFIER and PREDICT_XGB_CLASSIFIER_CLASSES functions used only the logit method to normalize the prediction probability of different classes. While these functions still use the logit method by default, this new parameter switches the normalization method to softmax.
