Missing one special icon

Hiho,

i’ve installed the plugin two hours ago and it works very well and the Buttons Looks quite good.

But unfortunetly there is one Icon that is not included and i don’t understand what i have to do to put it in the Editor.

I Need an “Car” Icon like this http://fortawesome.github.io/Font-Awesome/icon/car

Please could you tell me what i have to do for this.

Thanks a lot and Danke Schön 😉
Oli
