fixes a problem where an emptied cache from update_images won't be repopulated by the store
Add the data-abide="ajax" feature to the Abide documentation
Update topbar to work without jQuery Sizzle

The `> ul` selector is not valid for `querySelectorAll`. If I'm using a minimal jQuery build, `foundation.topbar` fails. This change uses `children` and `filter` to accomplish the same effect. As this is only running at init, I doubt there would be any performance implications.
Don't fail installing rAF polyfill if jQuery.fx isn't present

When using a minimal jQuery build, `jQuery.fx` might not be available. This patch checks to make sure the namespace exists before trying to overwrite the functionality.
I started to try and fix assuming tooltips were on mobile if the browser registered touchstart, ended up making all tooltip settings per tooltip, as well as make tooltips behave based on event type, not on browser registering touchstart
Clean up the code a bit. Should allow you to switch to a mouse based input type even if you opened it using touchstart. Clicking on the data-tooltip element via touchstart will now close it so you don't have to click on the tooltip itself
Better handling of switching between touch and mouse events
A little bit of cleanup.
Update foundation.interchange.js to work with background-image

When a tag(not an image tag) has a data-interchange attribute containing an image path it will set a background-image on element instead of trying to replace the innerHtml.
Should fix #4053

Don't use this.outerWidth since this doesn't reference the element the tip is supposed to be pointing at.
Modified Orbit to support reflow to allow for sizing recalculation when initially hidden

Remove setting size for embed and object

Setting height: auto; for embed and object causes errors with rich media ads if the ad partner is setting the height at the attribute level. See comment https://github.com/zurb/foundation/pull/763#issuecomment-31139717
