GSoC 2014 week 5

As the project has now come to the mid-term evaluation, I've almost completed my first two tasks, as I planned initially. Still I'm getting some feed-backs for the changes I did, but in overall, I've successfully covered all tasks.

Now with the new designer page, a user can:

• create new pages 
• edit a page
• delete a page
• save changes to a new page or an existing page
• export pages in various formats.

With these changes done, we can remove the existing "Edit or export relational schema" functionality from the phpmyadmin.
