MediaWiki translator, aimed at Wikipedia/WikiBooks type of web pages.
Syntax defined by http://en.wikipedia.org/wiki/Help:Wiki_markup
and http://en.wikipedia.org/wiki/Help:Displaying_a_formula.
The prefix m in the name mwiki distinguishes this translator from
gwiki (googlecode wiki).
Not yet implemented:
mwiki_ref_and_label (just using code from gwiki)
Just using plan ASCII solutions for index_bib (requires some work to
port to MediaWiki, but is straightforward - use rst as template) and
exercise (probably ok with the plain solution).
