Add way to set custom Transport on http.Client

Clients often need to connect to servers who may be using self-signed certificates. Currently Barrister uses the default http.Client which means connecting to these servers will fail. It would be useful to be able to pass in a custom Transport.

Here is how I have fudged things for now in barrister.go:

func (t *HttpTransport) Send(in []byte) ([]byte, error) {
...
tr := &http.Transport{
  TLSClientConfig: &tls.Config{InsecureSkipVerify : true},
}

client := &http.Client{ Transport: tr  }
