 * Chnage Log:
 *   v 0.4
 *   -  Removed a extra comma in options (was breaking in IE and Opera). (Thanks Jason)
 *   -  Removed the parameter name from the initialize function
 *   -  Changed the way expires date was being calculated. (Thanks David)
 *   v 0.3
 *   -  Removed dependancy on json.js (http://www.json.org/json.js)
 *   -  empty() function only deletes the cookies set by CookieJar
