Title: Removed CaptureHelper#flush_output_buffer as it is only used in tests.

reviewed: @tenderlove

cc @jeremy -- you introduced this in 2009, but it looks like it was never plugged into anything. It requires the OutputBuffer to conform to String while StreamingOutputBuffer doesn't implement those methods. Are we using this anywhere?
