Restrict comment display to res0l.net.

Disqus sets a bunch of state the first time a
comment thread is loaded, and behaves badly if this

Extract disqus thread id into a parameter.
Pad out the 404 page.
Add an animated 404 logo.
Chrome doesn't appear to support chained animations.
Remove unnecessary data from logo.
