Introduce Mill Tags

[xeodou]

We bring the a new useful feature to Mill this week, which is tags. We support tags for every blog post now, just like other blog engines. But we are different, mill-tags is base on the github labels. Every github issue can have lots of labels, and these labels will translate to mill-tags. Here are some quick steps help you create your own mill-tags:

• Create your labels on github at this page , like Announcement.
  
• Assign your labels to your blog post at here:
  

Mill also allow you set some private tags. Every labels on github start with _ will be filtered by mill engine. These labels won't show on the blog, but only show on github label list.

_Contributions are welcome!!_
