        * whoisi/test_controller.py: New test controller that is used by
        the etag support handling.

        * whoisi/controllers.py (Root): Add a test/ controller.

        * tests/twisted/network/test_download.py: New tests for etag and
        last-modified.

        * services/command/exceptions.py (NotModifiedError): New
        NotModifiedError that's thrown when a download gets a 304.

        * services/command/download.py: Add support for setting and
        handling etag changes in the http support code.  Not quite right
        yet, especially with handling redirects and etag/last-modified,
        but getting close.  You can set etag and last-modified via the
        DownloadCommand now.  If it gets a 304, it will throw a
        NotModifedError exception you can handle in your command error
        handler.  Is a lot cleaner approach than the old monkeypatching
        method.
