Support for other types of regression (e.g. count:poisson and reg:tweedie)?

While I can get the package to work with these kinds of models, the stated predictions don't match when the model is not reg:linear (using "regression" type). Would it be possible to support these types of regression?

The summation of the rows of the output of the "explainPredictions" function provides the prediction in regression tree. I don't know the algorithmic reason for this.
