Subject: PNG versions of valid HTML images added

I added PNG versions of each of the valid HTML images:

and changed the HTML blurb given for successful validations to:

      <a href=""><img border=0
         alt="Valid HTML 4.0!" height=31 width=88></a>

so content negotiation will return PNG versions to browsers
that understand PNG, and GIFs otherwise.

I had to add "Options +MultiViews" to Apache's httpd.conf
to enable content negotiation, and I also uncommented the
"CacheNegotiatedDocs" line to allow proxies to cache
negotiated documents.

More info on Apache and content negotiation is here:
