New issue 330: Integration with `setup.py test` should not require `virtualenv` to be installed

Peter Bittner:

In my Python projects I want to separate the requirements only needed for testing cleanly from the actual project.

The beautiful thing of tox is I can specify all those additional requirements in the tox configuration (tox.ini), and with the [integration in setup.py](http://testrun.org/tox/latest/example/basic.html#integration-with-setuptools-distribute-test-commands) it's possible to not even have tox installed to execute tests.

Actually, this is the theory, because unfortunately, running tests with `python setup.py test` still requires one dependency to be installed beforehand: `virtualenv`

## Current Behavior

``` bash
$ python setup.py test
running test

```
When I run `pip install virtualenv` the same testrun runs like a charm.

Is this a problem of tox, or and issue of setuptools?

## Expected Behavior

After having set up tox with [setuptools integration](http://testrun.org/tox/latest/example/basic.html#integration-with-setuptools-distribute-test-commands)
it should be possible to run `python setup.py test` to execute tests driven by tox
without having had to install any requirements (such as `virtualenv` or `tox`) manually beforehand.

## References

This problem is also documented in [issue #245](https://bitbucket.org/hpk42/tox/issues/245/can-not-install-sure-dependency-in-tox#comment-26884414).
