David Goldblatt d4f3f9a03f Beef up travis CI integration testing ... Introduces gen_travis.py, which generates .travis.yml, and updates .travis.yml to be the generated version. The travis build matrix approach doesn't play well with mixing and matching various different environment settings, so we generate every build explicitly, rather than letting them do it for us. To avoid abusing travis resources (and save us time waiting for CI results), we don't test every possible combination of options; we only check up to 2 unusual settings at a time.		2017-02-21 12:45:59 -08:00
