update Django version number accordingly

Thank you for the write-up! Following are my suggestions for corrections.

- Pin version of Pyramid to 1.7, else pip will install the latest release on PyPI. This will future-proof your instructions and make them consistent with your Required Tools.
- virtualenv and pip do not need to be installed with Python 3.5 because it now includes venv and pip. You do, however, need to update both. You'll need to update your PNG, though.
- Use `python3 -m venv` to create a virtual environment, as this is now the recommended way, although it is not yet documented, per https://bugs.python.org/issue27285
- Use proper term for a Python virtual environment. venv, virtualenv, and pyvenv (which is merely a script that wraps venv) are all implementations of a virtual environment.
- Use official, canonical URL for Pyramid docs.

Although I did not include it in this PR, I thought I would mention that Pyramid comes with three scaffolds—starter, alchemy, and zodb—the latter two of which have full tutorials at http://docs.pylonsproject.org/projects/pyramid/en/latest/tutorials/wiki2/index.html and http://docs.pylonsproject.org/projects/pyramid/en/latest/tutorials/wiki/index.html Additionally, we now have four cookiecutters that perform a similar function to the scaffolds, but go further by simplifying the entire installation process. Those are located at https://github.com/Pylons/?utf8=%E2%9C%93&query=cookiecutter
