Title: Turned helper classes into mixin

Changes:

- Removed _helpers.scss
- Split classes into _imageReplacement.scss and _hide.scss
- Wrap classes around a mixin
- @import the new SCSS files in _screen.scss
- I didn't add @include to trigger the mixin. I thought it's better to leave that to the individuals otherwise they'll end up including CSS they don't use in their output CSS.
