Add export to Markdown for Character Generator

[smutt]

My group uses a Mediawiki instance to manage our campaigns and it would be absolutely wonderful if I could import NPCs directly into it. So an export functionality directly to Mediawiki syntax would be great.

If not Mediawiki syntax another Markdown syntax would also be useful as it is usually easy to convert between different Markdown syntaxes. It doesn't necessarily matter how it looks so long as it represents the information well. It doesn't have to look exactly the same as the HTML.
