CLC-1510 - Investigate changes foundation 4.0.4 to 4.0.8

Biggest changes:

 - New base-font-size property - set to 13px
 - Added margin to bottom of buttons - set to 2px
 - Spacing changes
 - All the styles on .button are now also on <button
 - -webkit-font-smoothing: antialiased; is now disabled by default and we could use the "antialiased" instead.

Question to the designers: Where should we be using "antialiased" fonts?
