Font Awesome 5 support

@ryanck the bonus in the Option Set SVG icon approach is that when displaying the icon you can Get an Option: AppIcons: MyIcon:find & replace and replace #000000 with whatever colour you need based on your primary colour or the status of the icon (enabled, disables, pressed). In fact I tend to replace the color embedded in the SVG with #color then I search for that and replace accordingly.
