Add CartoDB Viz for weapons export companies

add links to the new nav
Remove interaction try

the viz type clustered does not allow interaction. need to be changed to
another type inside cartodb
Add CartoDB libs to layout file
Make sure second row is left aligned

when the first item is active is has a border and therefore 2 pixel
greater than the rest, floating will fail
add a "invisible" border to the rest to align the height of all items
