Title: Add --color=no to py.test cmd

Issue #11 comment by @gabehollombe where color=yes breaks Pytest.vim

if you have a pytest.ini that sets color=yes, you end up with control characters in your output.
this breaks the regex for parsing the results, and you never have any failures as a result. passing --color=no
should remove this issue.
