I made a few more small modifications to this branch:
 * make the test_http_has() test verify that a HEAD request is issued
 * make HttpTransport.has() issue a HEAD request rather than a GET.

I realise that there are plans to do a wholesale replacement of the
HTTP transport, but the change to use HEAD should help reduce the
bandwidth usage a little til then, and the tests would probably still
be useful with a new HttpTransport implementation.
