Add color swatch to color options

[bravomartin]

When you add options to a input of type color, it shows the hex values but no preview of the color.

It would be nice to show a swatch of the color alongside the color number.

With the current setup (system's select / option ) it would only be possible to do for the selected option (not while selecting). To overcome this we could move away from the system select and instead use a react-based one like react-select to be able to show a color swatch alongside every color option and do fancier styles for the option list.
