Add --once flag

Changes

• Require node >= 4.0
• Start using ES6
• Add --once flag that if used will not create a comment if a comment with the same body has already been made.

# Example

Comment created.
$ issue-comment --once blamattina/github-hotline#1 Looks good
Not created. A comment with this message already exists.
