Add weibo options for author in default template

[lufengd3]

I have opened a issue just for add a weibo option in default template at first, but I forget cleaver is for presentation when I modify the template -_-||
I did that because I just watch a slide on others blog at that time...
In my opinion, the default template is pretty good but lack of some options. I hope to add a "weibo" option for we chinese user.
Add such code under the "twitter" field in cleaver / templates / author.mustache

{{#weibo}}
    <h3 class="weibo">
      <a href="http://weibo.com/{{{weibo}}}">{{{weibo}}}</a>
    </h3>
{{/weibo}}
