Subscript and superscript markup à la MoinMoin

[Juanma Barranquero]

A trivial implementation of ^superscript and _subscript markup à la ​MoinMoin, from which TracWiki already draws heavily (and proudly :)
Included also a wiki-tests.txt patch, untested. (I asked this before, BTW, with no answer: what's the procedure to run the tests on a Windows environment?)
Anyway, the patch:
