Handle MediaWiki categories

[peterjc]

e.g. [[Category:Cookbook]] (generally as the last line in a page) flagged it for inclusion in the special wiki page .../wiki/Category:Cookbook.

Can we map these to Jekyll tags in the markdown header?

Looks doable, e.g. http://www.minddust.com/post/tags-and-categories-on-github-pages/

We'd likely need something like this in the ``wiki/Category:Cookbook.md` file,

{% include Category_Cookbook %}

which would need a matching file _includes/Category_Cookbook to generate the list of all pages tagged with this category.

Now that I stopped ignoring the category pages in the conversion script, they are converted and exist as files e.g. wiki/Category:Wiki_Documentation.mediawiki or wiki/Category:Wiki_Documentation.md - and any text on the page is of course converted. What is missing is the automatic links to all the pages tagged with that category which MediaWiki would had added to the end of the page, meaning they are not yet very useful.

However, links on other pages to the category are breaking due to the special colon syntax, which I think is best fixed from pandoc: jgm/pandoc#2849

Failing that, we could pre-process the MediaWiki files before giving them to pandoc, or post-process the MD files from pandoc?

I've been reading http://jekyllbootstrap.com/lessons/jekyll-introduction.html and while Jekyll has categories, they are hierarchical (you can't put a page in two different categories). e.g.

---
title :  Hello World
categories : [lessons, beginner]
---

Here you would get a single nested category "lessons/beginner"

Jekyll tags look like a better match to MediaWiki categories, e.g.:

---
title :  Hello World
tags : [lessons, beginner]
---
