fix Twirl example to correctly render in a browser (#189)

## Issue

When I tried the Twirl example in my browser, I noticed the HTML wasn't
rendering. This is due to the `Content-Type` header coming back as
`text/plain` instead of ` text/html`

## Change

I build a full cask.Response object so I can set the content-type
header. Ideally there is a better way to set this up. As I'm only just
poking at the framework I'm not sure what the best way is, but I'm
submitting what worked for me.
