v0.0.4

• Fix the usage documentation
• Escape newline characters in all logged values. Previously, you could generate
  multi-line log statements. This should never be the case.
• Add support for auto-generating exc_info parameters. If the log record is
  generated with exc_info, as in when using logging.exception(...), the
  log message will contain properly formatted exception and traceback information.
• Add support for logging with an empty message dictionary.
