Requires end to end unipony experience

When a user experiences total website failure we should ensure that they have only happy feelings about their obvious abuse of a drupal installation. Using something like:

register_shutdown_function('rainbowsod');
function rainbowsod() {
  print '<img src="http://drupal.org/files/images/UNIPORN.preview.jpeg" />';
}

would help end user experience tremendously.
