Story: I want to have all Phragile tests run automatically on every commit on TravisCI.

Details:
It is very difficult to run the Phragile integration tests at present, since they require a working Phabricator + Phragile setup. That is quite a hurdle for new contributors to overcome. Hence having the integration tests (which are basically all tests at this point) run automatically on a CI server is very valuable. People can then skip the local setup step for cases where this is not worth the time and effort. Also, having an automated setup of the dependencies is a nice way of documenting how people can do this themselves.

It's probably worth looking into if we could just use the Phragile Vagrant on TravisCI. It would include a working instance of Phabricator.
