Organizing variables on wiki

[Marcus Clyne]

Hi,

I've been looking through the Nginx source code and added some variables 
to the wiki.  I sometimes wasn't sure where to put them, and it didn't 
seem easy to view all the variables in the documentation at once.

Maybe, if someone has the time, a script similar to the one for viewing 
all the directives (but for the variables) could be created - and put on 
the same page, perhaps.

Just an idea.

Cheers,

Marcus.

P.S.  Cliff - good work with the new wiki.  It's looking really good.
