LibFMClassifier: Misspelling UseConstant gives different CV results about stacknet

@kaz-Anova Ahh, I see. The "Parameter's File" section in the README uses lower case, that's what was throwing me off. Thanks.

Hey @brandenkmurray . Thank you for letting me know . This is what happened :
The default value for UseConstant=True; so if you misspell or don't include this, you get True by default.
However when you give the parameters (in all cases, not just in Libfm) , the model understands only 'True' with uppercase 'T' not 'true'. If it is not 'True', the model thinks it is false. This is how it has been set up. You can see in the parameter files all 'Trues' are with capital 'T'. I will change it in the future to include lower case. For the meantime, please use 'True' if you need a feature and not 'true'.

That should be fixed now.
