Merge pull request from minrk/captureio...

Merge pull request from minrk/captureio New `%%capture` cell magic captures stdout/err while running a cell. Uses `capture_output()` context manager, moved to utils.io from IPython.parallel testing utilities, where it originated. The caputre objects can be printed as a string, case in which they display the captured stdout, which is also available as `.stdout`. The captured stderr, if any, is in a `.stderr` attribute. A `.show()` method can be called to quickly print both, with stderr being correctly printed to the sys.stderr stream (so the notebook displays it with red highlighting). closes

      """These kinds of tests are less than ideal, but at least they run.

      This was an old test that was being run interactively in the top-level tests/

      directory, which we are removing.  For now putting this here ensures at least

      we do run the test, though ultimately this functionality should all be tested

      with better-isolated tests that don't rely on the global instance in iptest.
