Half-Star Addition: Karl Swedberg
Demonstration: http://examples.learningjquery.com/rating/
Usage: $('#rating').rating('url-to-post.php', {maxvalue:5, curvalue:0});

arguments
url : required -- post changes to 
options
  increment : 1, // value to increment by
	maxvalue: number of stars
	curvalue: number of selected stars
