Bug 944005 - A minimal api implementation which passes the clobberer client's tests

This is the most basic implementation of clobberer as it does not include a front end, docs, or endpoints which are not used directly by the client. *note* It fails some tests; but it fails the _same_ tests as the current back end. Clobberer client tests will need to be re-written.
It shouldn't be; but I can explicitly set to text/plain. The client just consumes the output from a urllib2.open.read() and is happy with this return. I'll be rewriting the client after the old clobberer is replaced so that it consumes json.
