Revert "No need to store the version in a separate file."

This reverts commit a8373a2 and fixes #3.

If we import times from the setup.py file, it'll require pytz to be
available at install time, which we should not be wanting.  Therefore,
I've reverted back to the state where I simply import the version number
from the version.py file directly.
