Commit hook

Here is my pull request.

I realize after I completed the ability to change version numbers that the request was to allow the users to do this in the back end when creating a page.  I f I had a bit more time, i would have created a custom field for pages that populated using the version numbers saved in the database, the user chooses the number, and it shows that version number at the bottom of the page in bold red.

The page is at http://uptrending.cstef.com/

The footer is currently showing the number of commits to date.
