IMPROVEMENTS

• hash_valence_shifters added following negators: "daren't", "hadn't",
  "needn't", "oughtn't"; the following amplifiers: "absolutely", "considerably",
  "decidedly", "especially", "majorly", "most", "uber"; the following
  de-amplifiers: "almost", "kind of", "kinda", "partly", "somewhat", "sort of",
  "sorta". In addition, all contraction negators were re-added
  to the hash_valence_shifters sans apostrophe as cleaning or less formal
  writing may result in contractions without apostrophes.

  hash_sentiment_huliu, & hash_sentiment_sentiword and added as an amplifier
  to hash_valence_shifters. Spotted by AbdulMajedRaja:
