The SelectionSlider widget has a very similar interface to the FloatSlider and IntSlider, but is missing the handle_color style. This adds it. Seems to work for me, but I'm not super familiar with UI coding and don't know how to write tests for this. I don't see tests for this feature implemented similarly on the FloatSlider. If this needs a test, please point me to a test for something similar and I can probably figure it out. Thanks!
