New overflow-hidden utility class?

Created by: sts-ryan-holton

Hi, I'm suggesting another simple feature here for Bootstrap. Often I find in some projects I'm needing to set overflow to hidden to maintain consistent sizing or as part of jQuery functionality, I often find either having to set overflow on either the horizontal axis or vertical axis.

I was thinking we could possibly create some helper classes like this - overflow-*

Such as:

.overflow-y {
     overflow-y: hidden
}

Any possibility of getting some base functionality in place for this? We could possibly make use of SCSS variables to choose either hidden or auto for example.
