v0.18

• \inputpygments now checks inputted files for modification, so that
  typeset code will correctly update when the source is changed (#162).

• Julia now uses project flag "--project=@." (#157, #158).

• Fixed bug in processing Pygments options (pygopt) when a key is used
  without a value (#181).

• Some error handling for Windows was incompatible with other operating
  systems: replaced checks for WindowsError with checks for OSError
  (#177).

• Rust support is now compatible with document and working directory paths
  that contain spaces (#167).
