Fix exporting of a redirect. The view method in the Redirect sets

a HTTP header and returns "1", which doesn't create a redirect.

I fixed this by:

- Writing a exportHtml_view method just for Redirect.
- using the Fail Safe style template to output an empty page
  with a redirect tag in the header.
