This builds on/is an alternative to #92, and adds support for a working py3.9 test today (which, happily enough, already passes).
The python 3.9.0 tarball isn't available yet from travis, so this PR sidesteps the issue and sets an independent PYTHON_VERSION var (since the travis python install isn't actually used by the tests). If desired, in a few weeks when the travis people get around to building the 3.9.0 tarball, 72745ae can be reverted to make the config for the 3.9 travis job identical to the rest of the travis jobs, but it shouldn't make a difference
