Nav-bar dropdowns not working

[cjmox]

Default appearance of theme when activated from the latest version is the Foundation top-bar. You'll notice dropdowns work as expected.

To see the issue, comment out add_theme_support for top-bar (default) and uncomment add_theme_support for nav-bar in config.php

Nav-bar will appear, but dropdowns are no longer functioning. Suspected issue is in the way jQuery or Foundation navigation dependencies are being called. Check lib/scripts.php, templates/head.php, lib/nav.php, and lib/config.php to make sure I didn't do anything dumb.

Nav-bar markup seems to be consistent with the required markup given in http://foundation.zurb.com/docs/navigation.php
