It's not really temporary, so tmp isn't a sensible suffix.  It's
provided in the distribution of the package, so dist is.

Previously, the default configuration file was only provided in a form
that was not included in distributions.  This could potentially
frustrate users by making it difficult to find a configuration file
example.  To remedy this, I moved it to be a package resource, imported
pkg_resources (setuptools is now a dependancy!), and made Kaylee load
both the default and the local configuration files, with the local of
course overriding the default.

Since I'm migrating away from Github, keeping the old URL in future
releases doesn't make sense.

Now distributions created from setup.py put the systemd unit file in the
correct location for units provided by packages.  It may then be enabled
and started by the user with systemctl.

Closes #11.

Since I fixed a critical bug, I think a new version number is in order.

I finally got around to learning how to make a setup.py script.  I have
finally blossomed into a mature adult.
