Prevent the demonstratie default button styles from overriding panelizer and inline editing buttons.

Apparently something did not quite compile right in the css. Adjusted the styles to work as expected.

- Use a web font closer to that in the designs.
- Improve the collapsing functionality and stylability.
- Adjust the styles to have a more refined responsive layout.

This makes styling more stable and cleans up some of the generic styling on elements.

Perform an about face and completely change the design to one that works better on projectors and is more flexible. Changes include:

 - A lighter styling.
 - A collapsible menu.
 - Built in panel layouts.

These are all rough sketch changes as they are so drastic. They need to be committed at this moment so that features can be enhanced and tested along with the demo framework.
