Add a less-than modifier like the + modifier

[bbugh]

The plus modifier is really useful, and we're using :mq="['xs', 'sm']" in a lot of places for Bootstrap. It would be really helpful to have a - operator, so we could do mq="sm-" instead.

If this idea is acceptable (and are willing to merge in a timely fashion) I'm happy to provide a PR for this.

[StevenVerbiest]

I'm having the same 'issue'. Would be practical and consistent if this would be implemented!

[davision]

That would be great actually! Can anyone provide a PR?

[bbugh]

I'm happy to, but I've made so many PRs for open source projects that get ignored forever, I'd rather hear from @AlexandreBonaventure to confirm that they'll accept it before I spend the time on it.

[davision]

Yeah, let's wait for Alex to confirm.
