Fix colors in output of ResultList on Windows

Original Launchpad bug 515234: https://bugs.launchpad.net/ipython/+bug/515234
Reported by: ellisonbg (Brian Granger).

The ResultList that is returned by MultiEngineClient.get_result and execute does not handle colors properly on win32. This is because it is using print rather than Term.cout.

This can't be fixed easily because this text is not printed, but rather triggered on display.
