Add redirects for old urls

[mjhoy]

These redirects are for links in the paper "A History Of Haskell: Being Lazy With Class."

The createRedirects function produces html with meta tag redirects (source). I think this should properly handle the following URLs:

• https://www.haskell.org/humor -> https://wiki.haskell.org/Humor
• https://www.haskell.org/hat -> https://wiki.haskell.org/Hat
• https://www.haskell.org/development/views.html -> http://web.archive.org/web/20040107202217/http://haskell.org/development/views.html

Fixes #261.
