Add options for capturing output

* This resolves https://github.com/mdmintz/pynose/issues/11

To enable capture, set a Python env variable called "NOSE_CAPTURE" to "1".

It can be done like this in an ``__init__.py`` file:

python
import os
os.environ["NOSE_CAPTURE"] = "1"


This restores the default setting of `nose`, which is capturing output.
(Note that if output is captured, `print()` calls won't be seen.)

Capturing output can also be enabled with: ``--capture-output``.
