命令行更新 cnblog 博客主页副标题，可同步发到闪存或随笔评论

事情是这样的：

我喜欢把博客的副标题当作 qq 的个人签名那样用，没事把心情发到副标题上。并且可以查看以前发表的心情。

但是网页操作需要设置好些步，太麻烦。

先是打算把心情同步发到某篇随笔的评论上（cnblog 的日记不支持评论），然后发现自己的评论会把最新评论给刷了。

随后发现 cnblog 的闪存，同步到这上面不错，http://home.cnblogs.com/ing/，还能即时收到网友的评论。

使用示例：

➜  ~  cnblog "超级塞亚人 孙悟空"
login cnblog successfully.
update subtitle successfully.
post shancun successfully.
➜  ~

查看博客副标题、闪存，会发现已经更新。

将上面代码保存为 cnblog，把其中的 username，password 改成自己的，加上可执行权限，即可像示例那样使用。

将该程序添加为自定义命令使在任何地方可运行，详见 linux 添加管理自定义命令。
