Fix for two errors in _sub-nav.scss

1. sub-nav-active-bg-color was hard-coded. Now it is set to proper value
from _settings.scss

2. the hover color for the sub-nav-font was erroneously set to a
background color. Now it is set to the proper value from _settings.scss.
Fix dropdown buttons using HTML button tag were not displaying the pip
Re-initialization cause multiple 'Back' links
Update anchor tag with required "data-reveal"

As described here:
http://foundation.zurb.com/forum/posts/258-reveal-problem-with-foundation-5
"data-reveal" is required to have reveal plugin working properly. This example works nice as is but if you have your buttons (anchors) loaded with jQuery (DOM update after document ready) it will not work.
Let's save devs time with this tip in the documentation.
Thanks!

Fixes #4186 which was caused by commit da1a87af6d068b956b84353a9ee410fef89a9b1f. The issue is that I had it closing the dropdowns on click, which toggle() wasn't expecting.
