Serve a page for a given HTTP error.
This works by rendering a template based on the HTTP error code; so an
error of '404 Not Found' will render the '404.html' template. The
context passed to the template is as follows:
`request`
: The `webob.Request` object for this HTTP request.
`is_index`
: A boolean indicating whether or not this is the index page. This may
be useful in error pages where you want to link back to the home page;
such a link will be useless in the index.
`status`
: An integer representing the HTTP status code of this error.
`reason`
: A string of the HTTP status 'reason', such as 'Not Found' for 404.
The template is assumed to be valid XHTML.
Note that the templating machinery is only invoked when the browser is
expecting HTML. This is determined by calling
`request.accept.accept_html()`. If not, an empty response (i.e. one
without a content body) is returned.
