腾讯登录加密方式的java实现，使用这个就不用再用jsEngine来做MD5加密
2012-6-13号更新可用。
另外，登录链接已改成如下：
get=new HttpGet("http://ptlogin2.qq.com/login?ptlang=2052&u="+Config.USERNAME+"&p="+pass+"&verifycode="+checkNum[1]+"&low_login_enable=1&low_login_hour=720&aid=46000101&u1=http%3A%2F%2Ft.qq.com&ptredirect=1&h=1&from_ui=1&dumy=&fp=loginerroralert&action=1-2-11125&g=1&t=1&dummy=");
成功返回：
ptuiCB('0','0','http://t.qq.com','1','登录成功！', 'roy');
