Updated CI to expose a bug in bilby_result for python2.7, then fixed it

See merge request !601

`python setup.py install` is not exactly the same, `pip install` validates more of the metadata

python2.7 won't allow it because print is a reserved keyword

1) Add support for color output on the terminal
2) Move print to a separate function
3) Make print work as a "match" rather than exact-match only
4) Allow results to be passed either as a positional or optional arg
