Option to spew subprocess streams during tests...

Option to spew subprocess streams during tests This supersedes PR . Run the tests with '--subproc-streams show' to show output from subprocesses (kernels, IPython.parallel components) in the terminal, or with '--subproc-streams discard' to send it to /dev/null. By default (or with '--subproc-streams capture') the output is piped, captured and displayed only when tests fail. But in some situations, a test fails because of an error which actually occurred earlier, so you have to see all the output.
