Create placeholders comment sub for common nav styles

[getdave]

.nav-primary {

    > li > a {
        @include rem(font-size,16px);
    }

    a {
        color: #fff;
    }

    .sfHover > a,
    a:hover,
    a:focus {
        background-color: #4a4a4c;
    }

    .sf-with-ul {
        &:hover,
        &:focus {
            @include box-shadow(1px 1px 1px black(0.5));
        }
    }
}

.nav-primary {
    .current_page_item,
    .current_page_ancestor {
        a {
            background-color: lighten($navbar-background, 5%);
        }
    }
}

We repeat this pattern over and over. Add a comment stub in either _page.scss or create a new file to house "menu" styles for the site.
