Don't require accordion sections to be siblings.

This will allow accordions that have their sections separated into
different block-grid areas.
Improve documentation.
Add "slide_number" and "next_slide_number" parameters to orbit's before-slide-change event and callback
Update foundation.orbit.js

Since data-orbit-link does work on non-<a> elements when it comes to controlling the slideshow, the same should be true for updating the active link status for those elements (alternatively both should fail on non-<a> elements). Either way, it should be consistent. This proposal does the former, since I find it to be useful and can't see a reason why not.
Automatically generate visibility classes

Replaces most of the visibility classes with a mixin that simplifies
the process of adding or removing breakpoints and their associated
visibility classes. Resulting CSS is comprehensive without containing
any extraneous or nonsensical classes, and is far less error-prone.
Updated arguments to side-radius mixin in pre/postfixed buttons and pre/postfix spans and labels so that they work correctly when rtl.

Added a check for text direction when setting the background-position of the arrow on select elements.
Added support for fieldset[disabled]
New variable $topbar-button-top

It's impossible (or I didn't get it right) to center horizontally a button inside a topbar with a custom defined height.

Added a new variable $topbar-button-top to fix this issue
Added $topbar-link-padding variable
Made style adjustments to new visibility functions
Updating Offcanvas scroll issue
Merge branch 'master' of github.com:zurb/foundation
Separates legacy visibility classes in dynamic visibility class generator loop

Removes functionality to omit visibility classes based on relative
size, in favor of generating consistent classes. Separates legacy
visibility so they can be omitted.
