v0.12

• Added --cert-name flag to the certbot certificate request command.
  • This allows for both adding and subtracting domains to the same certificate file.
  • Makes it possible to have path names that are not domain names (but this is not allowed yet).
• Made the file parsing functions smarter so they only find unique file paths.
• Cleaned up some log output.
• Updated the docker-compose example.
• Fixed some spelling in the documentation.
