Updated DokuWiki code and tests to work with latest code from jgm.

The new code was got from inspecting changes in MediaWiki.hs

This slightly changes the output of Div blocks, but I'm not 
convinced the original behaviour was really correct anyway.

The code for handling Span does nothing for now, until I can 
work out the desired behaviour, and add tests for it.
