Config file updates. Mostly just playing with comments, but a few functional

changes:

1. Remove the directives in the document root <directory> section that
are there to handle the index.html.var and put them in their normal place
in the config file.  I see no reason to duplicate the directives and
explanations.

2. Change from the funky FilesMatch/SetOutputFilter to AddOutputFilter for
the SSI configuration.
