Update for stanford 3.4.1

[pabramowitsch]

Feel free to change or ask me to change anything.

Btw I was unable to rebuild bridge.jar (for my own edification). Tried various permutations, but gave up. I get a java compile error here.

AnnotationBridge.java:14: get(java.lang.Class extends edu.stanford.nlp.util.TypesafeMap.Key>) in edu.stanford.nlp.util.ArrayCoreMap cannot be applied to (java.lang.Class)
Object object = ((ArrayCoreMap) entity).get(klass);
