/**
 * jStrtotime Plugin for jQuery
 * @author: Michael Gilley <michael@180bydesign.com>
 * @site: www.180bydesign.com
 * @version: 1.0
 * @date: April 1, 2010
 * @dependencies: jQuery 1.3+
 * 
 * DESCRIPTION
 * Like it's big brother, the jDate Plugin, this is basically just
 * a wrapper plugin for Php.js' strtotime function to make date 
 * formatting and timestamps a breeze.
 * See http://phpjs.org/functions/strtotime:554 for the original
 * code.
 * 
 * USAGE
 * Unlike it's big brother, jDate, this plugin only include the 
 * jQuery function since I couldn't think of inserting timestamps
 * into DOM elements on a regular bases. Just use it like its php
 * equivalent (http://php.net/manual/en/function.strtotime.php).
 * 
 * EXAMPLES
 * $.strtotime('+1 month');
 * $.strtotime('+1 year 5 months 1 day 23 secs');
 * $.strtotime('+10 years', 1129633200);
