Fixes #1845 Span with label clips when wrapped on mobile
Add an example for accordion on both small and large screens

If you want accordion functionality on both small and large screens, without tabs, the `accordion` class is required. Without the accordion class, the [**javascript**](https://github.com/zurb/foundation/blob/master/js/foundation/foundation.section.js#L95) will add top padding to the section element.
Adjust .switch to only apply to div tags

This makes it match [the docs](http://foundation.zurb.com/docs/components/switch.html) and less likely to conflict with 3rd party plugins that utilize the switch class on other tag types.
