preventing duplicated imports

[jeffling]

Hi, we're trying to keep things completely modular and have each component declaratively import everything it needs. This causes things to be put into style.css multiple times (using extractTextPlugin), giving us a huge css file.

Is there any way of preventing this? I tried using scss-only hacks, like in https://github.com/zurb/foundation/blob/1a45d92be8af20bf6b3e8d28c12fdbc853205cce/scss/foundation/_functions.scss , but because sass loader is running node-sass afresh each scss that's required, the map in sass is not persisted.

#31 would solve this but it's a ways off. I ended up making sure that only mixins and variables and other pure sass code are used for imports.
