added JavaScript Reference for Responsive Toggle

[alfredbez]

In order to use the Responsive Toggle you need to include the file js/foundation.responsiveToggle.js

Are you referring to cases where people use the customizer, but do not include Responsive Toggle?

I use it like so in my gulpfile.js:

gulp.task('js', function() {
    return gulp.src([
        'node_modules/jquery/dist/jquery.js',
        'node_modules/foundation-sites/js/foundation.core.js',
        'node_modules/foundation-sites/js/foundation.util.mediaQuery.js',
        'node_modules/foundation-sites/js/foundation.util.keyboard.js',
        'node_modules/foundation-sites/js/foundation.util.box.js',
        'node_modules/foundation-sites/js/foundation.util.nest.js',
        'node_modules/foundation-sites/js/foundation.util.motion.js',
        'node_modules/foundation-sites/js/foundation.dropdownMenu.js',
        'node_modules/foundation-sites/js/foundation.accordion.js',
        'node_modules/foundation-sites/js/foundation.responsiveToggle.js',
        'node_modules/slick-carousel/slick/slick.js',
        'src/js/main.js',
      ])
      .pipe(plugins.babel())
      .pipe(plugins.concat('script.min.js'))
      .pipe(gulp.dest('js/'));
});

Given this page in the docs also talks about the responsive toggle, it makes sense to link in the jsdoc stuff, so I think this is good to go.
