Added raw data from mTurk experiments, processed data, made folders

Processed data were taken from Puns-master/NearHomophones and
Materials_Jan_2013/ModelAnalysis_v7. They contain mean funniness
ratings for each sentence (identical and near puns/non-puns), and
relatedness ratings/trigram probabilities of word pairs. The processed
data only contains original puns/nonpuns and not modified ones.
