v0.14

• Made so that the container now exits gracefully and reports the correct exit code.
  • More details can be found in the commit message: 43dde6e
• Bash script now correctly monitors both the Nginx and the certbot renewal process PIDs.
  • If either one of these processes dies, the container will exit with the same exit code as that process.
  • This will also trigger a graceful exit for the rest of the processes.
• Removed unnecessary and empty ENTRYPOINT from Dockerfile.
• A lot of refactoring of the code, cosmetic changes and editing of comments.
