Switch to Python3

Our servers have, in the two years since we last needed to change
statusbot, switched to installing packages with pip for Python 3.x
instead of 2.7. Instead of figuring out how to unfurl that, just
roll forward and embrace the glorious pastfuture.

Update the simplemediawiki version to pull in a prerelease, since
that's the only way to get a version which supports Py3K.
