Allows override of stdout/stderr/log capturing

Browse Source 
During a test run stdout, stderr and log messages are being captured. If
the test fails all three will be printed out so that can be inspected.
Each stream has an environment variable that can be used to stop it from
being printed at the end of a test run by setting its value to 0. This
is in line with what many of the other project are already doing.

Environment variables:

 - OS_STDOUT_CAPTURE for stdout
 - OS_STDERR_CAPTURE for stderr
 - OS_LOG_CAPTURE for logging

Disabling Stream Capture
~~~~~~~~~~~~~~~~~~~~~~~~
The stdout, stderr and log messages generated during a test are captured and
in the event of a test failure those streams will be printed to the terminal
along with the traceback. The data is discarded for passing tests.
Each stream has an environment variable that can be used to force captured
data to be discarded even if the test fails: `OS_STDOUT_CAPTURE` for stdout,
`OS_STDERR_CAPTURE` for stderr and `OS_LOG_CAPTURE` for logging. If the value
of the environment variable is not one of (True, true, 1, yes) the stream will
be discarded. All three variables default to 1.
For example, to discard logging data during a test run::
$ OS_LOG_CAPTURE=0 tox -e py27
