Just like the Windows wheels, these allow for Linux users to install
mwparserfromhell and use the faster CTokenizer without needing to
have build tools installed.

Under the hood, this uses pypa manylinux1 docker image to build and
tag the wheels, then publishes them to pypi if a new tag was pushed.

Fixes #170.
