Added the code for changing the status. Yet untested.
[completed] Admin Portal Completed. The administrator can now change the status of
the post. Although, there is no central place where all the approved posts can be viewed.

TODO: Create the main front end of the blog
Changed the homeData function so that the status can be given as a parameter to the function, in the future, this can be used to see posts that have been approved or posts that have been set to "Moderated. Further feedback required" without changing much.
