Integrate processing

Wanted the processing code to run in the same iframerunner as other scripts, had a heck of a time because it looked like it wasn't working. As it turned out, it was working but there was an extra <div class="content editor"> wrapping the result, so the iframerunner wasn't actually visible. That took way too long to debug, but for next time the clue was that the menus weren't showing up either.
