New issue 318: Allow wildcards to be used in TOXENV and with the `-e` option

Ed Morley:

Currently it's not possible to use wildcards with TOXENV and/or the `-e` option.

For example, I'd like to be able to use:
```
export TOXENV=py27-*
```
... to just run the python 2.7 subset of the peep tox config:

However since wildcards aren't supported, I've had to resort to a bit of a hack to generate the TOXENV in the Travis config:
```
export TOXENV=`tox --listenvs | grep "py${TRAVIS_PYTHON_VERSION/./}-" | tr '\n' ','`
```
