[PATCH] Remove deprecated Rainbows::HttpResponse

[Eric Wong]

Thanks!  Is the next version of Cramp ready-to-release soonish?

The test suite currently relies on 0.13 and it fails with this
patch applied, but cramp.git now relies on my latest changes to
rainbows.git...

So does the chicken or egg come first? :)

I will hold off on applying this patch until the next Cramp
is out, http_response.rb shouldn't break anything just by being
in the Rainbows! tree another release.

I suppose I can release the current rainbows.git as Rainbows! 4.2.0
today (a good version number :D) just for Cramp.
