New issue 174: Allow testenv to be "non-voting" (optional)
https://bitbucket.org/hpk42/tox/issue/174/allow-testenv-to-be-non-voting-optional

Alexandre Conrad:

I would like to see an option that tells tox to not fail for testenvs / jobs that are considered optional.

For example, if I have a section [testenv:pep8] I don't want tox to fail if I mark it as non-voting. So if a testenv returns a non-zero status (failure) then tox would still exit with a zero status but display a warning that a non-voting test failed.

```
#!ini

[tox]
skipsdist = True
envlist = py26, py27, pep8

[testenv]
commands =
        pip install -e .
        pip install -r test-requirements.txt
        py.test {posargs}

[testenv:pep8]
voting = False
commands =
        pip install pep8
        pep8 --ignore=E501 surveyservice/
```

If this is considered a good idea, I'd like to try implementing it.
