[klutz] Patch to show alternative image if comic does not exist.

[Paul C]

Hi,

I've just done a quick and dirty patch to comics.php.  Basically it uses
file_get_contents to grab the image as a string and if it fails (404) it
loads in a nocomic.jpg image in its stead stopping the horrible red X's all
through the listing.
