Changed script calls

- Changed head.php to call Foundation dependencies in order, trying to fix nav-bar drop down issue

- Changed jQuery to 1.8.2 from 1.8.3. Foundation is currently using 1.8.2, while current version of Roots is now on 1.9. Will change to 1.9 when Foundation upgrades

- Adjusted nav.php. Still having issue with nav-bar, while top-bar works fine

- Wrote an add_theme_support for nav-bar, issue unaffected and site still functions correctly
