Support returning any http_body::Body from IntoResponse (#86)

Browse Source 
Adds associated `Body` and `BodyError` types to `IntoResponse`. This is required for returning responses with bodies other than `hyper::Body` from handlers. That wasn't previously possible.

This is a breaking change so should be shipped in 0.2.
