Enhancement 166: moved icons used for faceting into faceting.scss

To keep the sprites file cleaner and prevent common use of the faceting icons, we moved the icon rules into faceting.

We also renamed the status class icons to not include "icon".  This will help us normalize our status classes across the board.
