Update jquery.flexslider.js

corrected spelling
Fix no/before js load issue when using custom selector

Changed '.slides > li' to '.slides > *' to prevent showing all slides before JS loads (or if it doesn't) when using custom selectors like {selector: ".slides > div"}.

Also removed .no-js from JS fallback to enable for users who don't have .no-js on body. No negative consequences as flexslider's inline styles overrule it. Also allows first slide to show if script file or plugin JS fails to load/run.
Flexslider.css Firefox negative margin bug
