Allow easy use of Font Awesome icons

[shocklateboy92]

The longest part of writing kargos scripts personally has been coming up with a decent looking icon, sizing it correctly and adding it somewhere I can easy reference it from my script.

There's over 7000 cool, high quality icons as part of Font Awesome. If Kargos already had them already integrated a script just needed to reference it, that would make the process much nicer.

Of course, Material Design Icons should also be a consideration.
