add a quiet option (-q)

[zoobab]

Hi,

After the vladiate 0.0.20, I could get the shell exitcode for success or not.

Now I would like to add a quiet option (-q) so that when I call vladiate, it silently validates, if not it will throw an error.

I think this is possible once #53 is merged.

@zoobab Are you suggesting that -q would suppress all printing and just return an exit code? Or do you think it should print an error only on failure? I think the former is probably the more common UX.

[zoobab]

Yes let's wait until #53 is merged.

I would not print anything on success (just grab the exitcode), and only output some error in case of failure.

Looks like #60 solves adds quiet option

The PR is actually in #62 and needs work, the original author seems to have abandoned it.

Can anyone do some work about this please? It would be very useful
