Hercules Edit Most Recent Post

Adds a direct link to publish the most recently published post to the Posts menu. I was trying to go in and edit my most recent post and I realized that it is something I do often. I normally have to go to the posts page and then press the link to edit the most recently published post. So I decided to save myself a step and add a direct link, thought others might like it too.

Maybe in a future version I'll provide options to add direct links to edit other recently published posts.
