Install Newest Versions of Python Packages

When no version for a package is specified, `pip` defaults to the newest available version. It seems an exception to this is the case when a requirement is already satisfied.

An example of this is given by the recent [Travis run](https://travis-ci.org/github/mdp-toolkit/mdp-toolkit/jobs/700398010#L365). Here we ran:

```bash
pip install numpy==1.16.2 scipy==1.1.0 scikit-learn==0.20.0 joblib==0.13.2 libsvm pytest pytest-cov coveralls future
```
which yields:
```bash
...
Requirement already satisfied: pytest in /home/travis/virtualenv/python3.7.1/lib/python3.7/site-packages (4.3.1)
...
```

Which results in this error:
```bash
pluggy.manager.PluginValidationError: Plugin 'pytest_cov' could not be loaded: (pytest 4.3.1 (/home/travis/virtualenv/python3.7.1/lib/python3.7/site-packages), Requirement.parse('pytest>=4.6'))!
```
I am proposing to fix this by adding the `--force-reinstall` option, which will reinstall all packages even if they are already up-to-date.
