Display tags/labels of blog posts

[lunkwill42]

#34 cleans up the tags of the blog posts somewhat. However, there isn't currently any template code to display post tags.

Tags do not need to be prominent in a blog post (they probably belong in an <aside> at the end of each blog post body). An HTML list of tags would do, and styled as grey-ish "labels" beneath each blog post (i.e. no need for fancy colors).

There is also currently no way to navigate posts by tag, but this is a separate issue.

Something like this after {{ .Content }} in full-blog-body.html might do:

        {{ if .Params.Tags }}
        <aside class="tags">
          <ul>
            {{ range .Params.Tags }}
            <li>{{ . }}</li>
            {{ end }}
          </ul>  
        </aside>
        
        {{ end }}
