Add Font Awesome Framework

It’s been brought up in a couple places, but not as an official request. And I know you guys intend to do it - but still.

The font-awesome should just be an additional framework you can add. More importantly - the icons need to show up in the App structure panel and there should be a way to just add an icon. I get this can be done in the DOM, but it doesn’t make sense to tell people that font-awesome icons don’t show up in the App Connect stuff because it is actually a part of Bootstrap.

Personally, I don’t mind using the DOM, but I think graphic designers especially will want it in App connect.
