pandoc-citeproc 0.8.1

• Improved performance in bibtex cross-reference resolution (#190).
• Take 'form' for date-part elements from date if not specified (#116).
  Previously if the 'form' were unspecified in a date-part
  element, it would go to the default 'long', even if the
  date as a whole was 'numeric'.
• Transform only uppercase ASCII letters in titlecase transform.
  This helps us pass one more citeproc test case.
• Cleaned up locator parsing code.
• Allow roman numeral locators (#173.
• Fixed missing dash between months in date ranges (#175).
• Fixed strip-periods (#185).
• Parse supplementary fields in CSL JSON "note" fields (#94).
• Support more biblatex markup in converting biblatex bibliographies:
  mkbibemph, mkbibitalic, mkbibbold, mkbibparens, mkbibbrackets,
  autocap (Nick Bart, #26). Treat reviews as articles.
• Add biblatex keys for additional languages (Nick Bart).
• Use HTTPS for DOI resolver (Andrew Dunning).
• Add biblatex keys for additional languages (Nick Bart):
  ca-AD, da-DK, es-ES, fi-FI, it-IT, nl-NL, pl-PL, pt-PT, pt-BR, sv-SE
