* Class for displaying HTTP server errors

* Note: The older util.php class simply printed a string, but the spec
* says that 500 errors should be treated similarly to 400 errors, and
* it's easier to give an HTML response. Maybe we can customize these
* to display some funny animal cartoons. If not, we can probably role
* these classes up into a single class.
