Expanded controller for custom icon

Expanded user controller to save the custom icon of individual buttons for the Button Editor.

I wanted to put the saving part into its own controller, but I wasn't able to implement this because I couldn't put two controllers on one page via the route in web.php, and to my knowledge this is impossible. So I had to do some trickery to get this working. If I hadn't implemented the if-else statement, one value couldn't be saved without a NULL error violation.

This will be used to display a custom icon via Font Awesome.
