Fix .ie-class mixin #SCSS

[ldexterldesign]

Hey,

I've had to comment out this line in settings.scss:
*zoom: expression( this.runtimeStyle['zoom'] = "1", this.innerHTML = "&#xf#{$pua};"); ~ https://github.com/zurb/foundation-icons/blob/master/foundation_icons_general/sass/_settings.scss#L13

... because it's throwing the following error:
Warning: /Applications/MAMP/htdocs/intracore_style_guide/scss/lib/foundation-icons/foundation_icons_general/sass/settings:11: error: error reading values after this

Regards,

PS Sass 3.3.11 (Maptastic Maple)
