Prevent IE6/7 box model problems.

Move the media query width statements to body rather than the
various full_grid elements that have paddings set in a modern
box model that IE6/7 ignores. Still occasional issues caused by
this, but nothing major or affecting readability, like they did
with the main layout ones.
