Reordering of SASS imports allowing easy necessary overrides

I also added the Foundation Visibility component to the list since this will allow us to hide for large all depending on the type (http://foundation.zurb.com/docs/components/visibility.html)

The reordering is also in relation to https://github.com/waynestate/styleguide/issues/1 since it will allow us to define the vars cascadingly overriding foundation.
