Font Awesome Update & Setting

This plugin wants to load Font Awesome 4.3.0 via https://maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css (enqueued as font-awesome).

I think it’d be helpful to have this updated to use FA 5.x or even 6.x now that this is available (5.x might be good for now since it does bridge the update a bit and not much has moved over to using 6.x yet.)

Additionally, I’d love to see a checkbox to toggle the inclusion of FA on public pages. I have FA being loaded in from elsewhere so having this also try to load Font Awesome can result in a redundant copy (which then might also have conflicting styles due to it loading an older version.) I know this can be done via wp_dequeue_style & wp_deregister_style, but I think it’d be nice if something like this didn’t need to have code added to handle this when it could be a simple checkbox on the existing settings page.
