Pyramid benchmark for Python 2 and 3

Pyramid, http://www.pylonsproject.org/

I've implemented all tests on Python 2 and Python 3. Perhaps someone could add PyPy, or I might later.

I've matched conventions for the setup hook. To run the application's own tests, run:

```
virtualenv .venv -p /usr/bin/python3.3 --distribute
source .venv/bin/activate
python setup.py develop
python setup.py test
```

Modify the -p for your distro or desired Python version.
