Moved and optimized images.
Moved stylesheets to Sass + fixed broken styles.

Modified markup to work with new styles (esp. form markup).

same as before.
Don't diff SVG files.
Formatted the Apache License v2 for the Open Sans font.
Repaired the social icons in the footer.

Also adjusted the "Learn more" button on the homepage,
which was a bit off to the left in Firefox.
A bit more responsive to smaller screens.

Added the a custom build of the ZURB Foundation 3 framework and
Normalize.css, and built ontop of them. Now fixes #33.
Merged 'develop' from whymarrh/aba-lookup.
