Title: Add output_handler class/argument for stream-based processing of output

As described in the comment on the other request, this design, while more complex, may be the best way to enable a superset of the console behavior. Sorry for the trouble. The tests seem to pass as well as they do for the revision where I forked. They really don't work well non-interactively, but this isn't surprising when graphics devices are involved. NEWS updated; includes some justification.
