Add force option

I originally was thinking about making 'results' into an object, but I didn't want to start re-factoring code until I got some input.

Another possibility would be to make these status codes, like the scss lint spec (0, 1, 2).

Thoughts? I'm open to anything.
Nope, that must've been a hold-over from testing. Thanks for pointing that out, I'll take care of it.
