Partial dependence plots throws exception for support vector regression solutions

[abeham]

To reproduce: Open a new SVM, load a problem, e.g. Housing, open the partial dependence plot.

The error message is: "System.ArgumentException: The variable MEDV does not exist in the dataset."

The problem can be reproduced.

r15854: don't include the target variable in the svm_problem when a trained SVM is used for prediction

[abeham]

I tested it and it works

r16160: merged r15854 from trunk to stable
