Hitchhiker's Guide Easter egg IA

I had this idea for a while but I wasn't sure if it was something you guys wanted around (still not convinced really, since its less helpful than it is fun [for me anyways]). Then I saw the GoT one so I figured why not. If you guys don't want to open pandora's box for stuff like this close this, I won't feel bad haha. If it gets merged I can always post it to /r/dontpanic to maybe spread the DDG love (to an extremely niche community). Or you could go the other way and I could work on something like a 'Response' goodie where depending on a query Dax could pop up and respond appropriately.

In fact, I don't think it will trigger with your primary example query as it is written.  I also like to see the guard cases do their returns before the work cases.  It doesn't really matter in this case, but it can make the maintenance easier in the general case (like maybe your up-coming all-in-one Easter Egger)

```perl
return unless ($_ eq '' || $_ eq '?');
return 'Forty-two', html => '<span style="font-size: 1.5em; fontweight: 400;">Forty-two</span>';
