v-0.8.0

• Many bug fixes.
• kuromoji is modulated. kuromoji[tokenize] or kuromoji[pos] now only performs sentence splitting, or pos-tagging (including lemmatization).
• CoreNLP is upgraded to 3.9.1; see the official release note.
• Support two new annotators:
  • benepar: a new neural state-of-the-art parser (95.07 F1 on English PTB test set).
  • stanfordtypeddep, which, given a (constituency) parse, converts it to Stanford or Universal dependencies.
  • Combining these two annotators together enables obtaining a state-of-the-art dependency parser on Jigg. By combination, I obtained "95.89%" UAS and "93.79%" LAS on PTB converted to Stanford dependencies.
