New quality measures for ClassificationSolutions

Description

The sensitivity and specificity should be calculated for classification solutions. Further interesting measures would be the precision, negative predictive value, false positive rate, or the false discovery rate.

r11683:

Classification performance measures improvements in terms of readablity of the code.
Added positive class value to the classification performance measures result collection.
Fixed bug: classification performance measures will now be calculated after loading from files with non serialized performance measures results.
