Set up CKEditor

This is the editor that's going to be used to incorporate ShareJS later
on! It works based on the text area.

To make it work:
 - Add the ckeditor.js link at the Head section
 - Add a textarea with a name and id of your choice
 - Include a script section below the textarea with - "CKEDITOR.replace('your-editor-id')"
