Some care and feeding of the wiki

Hello,

I spent some time today trying to get the Quixote wiki more
up-to-date.  My goal was to update all the pages for Quixote 2 but I
ran out of steam before finishing.  If anyone feels like it, here's
the list of unfinished work:

I've started updating Andrew's two tutorials as well.  If anyone
wants to pitch in, I can stick a repository somewhere.
