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!

Fixed a couple of inexplicable block grid display / syntax bugs
Added not() exclude for buttons within sidebars

To fix issue #4209, I've added the same sort of exclude as already used in _top-bar.scss to stop styles being passed to child buttons.
Fix orbit's events method

events method is using `self.name` but never defines `self`.
This causes the data-attribute to be called '-instance' (Instance)
instead of 'orbit-instance'.
