Changes:
- Added api/responses/notFound.js, an updated version of the notFound
response built into Sails that sets a `hideFooter` page local variable
to hide the website footer on the 404 page.
- Updated the styles and layout of the 404 page to match the latest
wireframes.

more modern layout.

* **Bug Fixes**
