Title: Return non-zero exit code when results include anything but all-ticks

This allows augur to be used in a CI environment. When you run the tests and they fail, `aug` will now exit with an exitstatus of 1, rather than 0.

I am not sure if you want to fail on *all* the non-green cases, but it seems the most logical imo.
