Delete a post

[stevebrownlee]

As an authenticated user, I would like to be able to delete any of my posts

Given that a person has provided proper authentication details
When the person is viewing the post feed
Then there should be a delete icon beneath each of the person's posts

Given the person wants to delete a post
When the person clicks the delete icon beneath the post
Then the post should be removed from the database
And the list should be displayed again so that the post no longer appears
