Title: Quickfix for nltk.classify.maxent: 

After this commit MaxentClassifier will use 'cg' algorithm if scipy.maxentropy is not available (instead of raising an exception). This should provide a quick fix for #307.

In the long run we should probably add sklearn.linear_model.LogisticRegression support to MaxentClassifier and make it default.
