Fixed instructions for using Foundation with an existing project
Change information about NARGA WordPress theme, using Foundation 4, approved on WordPress.org
The top bar has been modified to calculate height based on sticky / fixed
positioning element.  Additionally, rather than jiggering the height around
manually, the ability to add custom CSS rules for a Foundation component
has been added to the base Foundation.js (addCustomRule).  It also supports
the built-in media query names (small, medium, and large) generated by the
SASS compilation.

I also updated the docs to clarify the need for contain-to-grid and fixed
to be on the same element.
issue #3004
Dropdown hover example
avoid treating zero as a falsey value

This allows you to use : 

```
$(document).foundation('magellan', { threshold: 0 })
```
and not have it be overridden with some unrelated number.
Adjusted topbar menu caret positioning to allow for differing topbar heights
Now allowing override of -dropdown-label-bg
