Jeremy Ruston 9b2af13596 tm-http-request: Add support for binary responses
With a demo courtesy of https://random.dog/

@rmunn you recently worked on the base64 utilities. I tried to use $tw.utils.base64Encode instead of window.btoa, but found that it didn't work. It's concerning because we expose that utility method as a filter operation, and it would be frustrating if we were not base64encoding things properly.
