Handle hide-for-inline-*

[HugoHeneault]

Hello,

I'm using foundation for a while (thanks a lot for your great work, by the way), and I'm having an issue with visibility classes.

Assuming I have this code :

This is <span class="hide-for-small">some</span> text

On medium-up screens, it will display

This is 
some
text

Bootstrap 3.2 seems to handle this (twbs/bootstrap#12204). Could you add this to foundation ?

The way this is handled in generated classes for Foundation would (much like bootstrap) require some seriously verbose class names...and lots of them. Given that this doesn't occur terribly frequently we'd prefer to not add this as a generated option in Foundation and instead rely on the available mixins to do this.
