This makes sure we upload the same files to Github Releases and PyPI.
Currently we were building them twice, with the risk of different files
being uploaded to the two repositories.
This should speed it up a bit, as brew will download a pre-compiled "bottle", whereas pyenv compiles python from source.
The current 'python3' formula on homebrew is 3.6.0, so let's use that.
Previously we were using a separate Travis build that only run coverage with a single Python version (3.5).
Now, we run coverage with all python versions, and upload a combined coverage data to Codecov.io.
Since tox already creates its own test environment, so there's no need to create another virtual environment to install tox into.
This simplifies things a bit.

When I do `pip install -r dev-requirements.txt` from within a virtual env,
jython sits for 3-4 minutes doing nothing, then the Travis shell exits with this cryptic error:
/usr/bin/env: python2.7: Argument list too long
I don't know why but when I `pip install -r requirements.txt` on Jython,
it always raises a Java StackOverflowError.
If I install the deps individually, it works...
$ pip install -v -r dev-requirements.txt
