I have created this PR in replacement of PR #104. It adds a Delete button beside the Edit button.

As discussed here, it was observed that when a story is edited, the content changes and thus all the votes and comments may not agree with the new version of the story. So, it was suggested that a better option would be to unpublish or delete a story.

Also, I had previously made PR #104 by adding the feature to edit a story. But, as discussed in the mentioned PR, I was asked to add the Delete option.
