/**
* jQuery plugin for Pretty looking right click context menu.
*
* Requires popup.js and popup.css to be included in your page. And jQuery, obviously.
*
* Usage:
*
*   $('.something').contextPopup({
*     title: 'Some title',
*     items: [
*       {label:'My Item', icon:'/some/icon1.png', action:function() { alert('hi'); }},
*       {label:'Item #2', icon:'/some/icon2.png', action:function() { alert('yo'); }},
*       null, // divider
*       {label:'Blahhhh', icon:'/some/icon3.png', action:function() { alert('bye'); }, isEnabled: function() { return false; }},
*     ]
*   });
*
* Icon needs to be 16x16. I recommend the Fugue icon set from: http://p.yusukekamiyamane.com/
