Since `jQuery.event.add` can accept a handleObj there's no need to reiterate them as args, but we *do* need to set the `selector` variable correctly.

When stopping a show, save showing end state instead of start state to fix animation toggling issue. Fixes #10848.

also add smarttabs:true and fix some smarttabs spacing issues

Although #6911 fixed the case where event.target was disabled, it missed the case where the target was a sub-element.

Reformat jshint errors to be readable; make post-compile.js write directly to jquery.min.js; update required Node version

There's no reason to call quickParse if selector is falsy, so it's a minor performance optimization anyway. No change in behavior at all on our side, so no test case needed.

- Reordered some of css.js in preparation for jshint undef.
