Show only test failures

Hey, thanks for the hard work here. I have recently started adopting Smoke for the Juvix project at the Smoke branch. So, let me open a few issues related to our needs. I'll start by saying that, for larger projects, warning about only failures
comes in handy instead of the current output. The flag could be as follows.

-h --hide-successes   Show only test failures

Glad you're finding it useful!

I am considering moving to TAP output for the next major version of Smoke, which should make it easier to filter out useless output. Does that work for you?

[SamirTalwar]

Following up; do you think TAP would suit your needs?

TAP looks good.
