Always attach body to response object?

[iangreenleaf]

I'm trying to test an image request with tobi and want to check that the body is being sent correctly. Unfortunately, the params that are given for non html/json responses don't contain any way to get at the body (that I can see).

Would there be any problem with always attaching the body at res.body, like is currently done with json requests?

I'll code up a pull request if you like this idea.

#83 is probably related to this.
