[TxMt] Mediawiki bundle

[Charilaos Skiadas]

I had started a mediawiki bundle, which has not gone much further  
than copying from the markdown bundle, but at least one person asked  
me to make it available.
Since I am not really very proud of it as it stands, and since I am  
not planning to work on it much in the near future, I won't add it to  
the repository yet, but if you want to download it and use/improve  
it, point your browser here:
