Kh redesign

@boonrs adding my redesign changes. Everything is in redesign.html and redesign.css. Quite a bit has changed ...

- Incorporated new design
- Created new classes (infographic, info-group, info-title, etc etc)
- Used a flex-box model for proper alignment (these are the supported browsers: http://caniuse.com/flexbox)
- Added responsiveness
- Removed Nav (isn't really necessary for this amount of data, adds unnecessary UI complexity)

Next steps: 
- create a visual to explain how the model works
- template it!
- consider removing bootstrap entirely (I think there's only 1 bootstrap class I currently use)
- Add options to share
I meant re-add options to share. The old share options broke with the redesign so I decided to comment them out and fix in a separate pull request. In order to do this I need to ...

- Re-create the sprites
- Fix the "share_this" css class
- Make the "share_this" div visible on all screen sizes

In addition, we had talked about being able to share each section of the infographic individually. That's a lower priority to me if we get the basic sharing fixed.
