ppgames v0.8.1

New features

• New function save_pocketmod() which is an alternative to save_ruleset()
  that saves the ruleset as a "pocketmod" booklet (#110).

• New function names_rulesets() lists the games we can generate rulesets for (#144).

• save_ruleset() / save_rulebook() can now export to non-pdf formats using pandoc (#76).
  We can customize pandoc output using the new cmd_options argument, by default
  we try to pick reasonable defaults based on the file extension and whether its a book or ruleset.
  Quality varies for the various output formats but html, epub, and docx export looked "okay".

• save_ruleset() / save_pamphlet() / save_pocketmod() support new arguments game_info, game_files,
  and save_promo_fn (#115).
  This allows users to generate rulesets using files not located within the {ppgames} package.

  Creative Commons license info into pdf output (#71).
  Requires suggested package {xmpdf} and the command-line tool exiftool.

• We now export normalize_name() which normalizes game names into a standard format
  for use in R/LaTeX variable names and for use in filenames.

• We now export save_promo_image() which saves promo images for games.
