Round style swatch

 From:  Moi3dFan

I'm a big MoI3D fan! I want to customize the color swatch a bit. I was able to do this in EditStylesDialog and in Context Area via CSS in the ".SceneBrowserSwatchActive" property border-radius:30px, but in BrowserPanel they are still square.

I don't understand anything about CSS. Help me figure out how to round color swatches.

Thank you!
