xstatic-hogan has never been released using the OpenStack release
prociess with openstack/releases repository.
To sync the release history in openstack/releases and PyPI, we need to
release a new version, so the xstatic version is bumped.
README is also updated to match the length of the title marker
to the length of the title.

We want to default to running all tox environments under python 3, so
set the basepython value in each environment.
We do not want to specify a minor version number, because we do not
want to have to update the file every time we upgrade python.
We do not want to set the override once in testenv, because that
breaks the more specific versions used in default environments like
py35 and py36.
