jQuery 1.8+ incompatibility - stars highlighted when there is no rating.

This is because of a slight change in the way jQuery handles negative numbers in the :lt() selector - prior to 1.8 negative number select nothing, but 1.8+ items are unselected from the end of the array (consistent with the behaviour of slice).

I've created a JS fiddle at demonstrate this:
jQuery 1.6 - http://jsfiddle.net/Z5QYz/
jQuery 1.8 - http://jsfiddle.net/Z5QYz/1/
You'll see in the 1.6 version none of the divs are selected, while in the 1.8 version the last one is.

The attached patch fixes this (and still works with previous versions of jQuery), and removes lt selector in favour of slice - this is better for performance (see 'Additional Notes' at http://api.jquery.com/lt-selector/).

EDIT: I also posted a bug for jQuery Docs, which have now been updated with a 'Prior to jQuery 1.8' note explaining the above.

Issue #2130495: The default value is wrong with jQuery 1.8 was opened as a duplicate of this.
