Make the oscilloscope colors available as properties so that they can be changed via style sheets. Adjust the existing styles to use the colors that have been hard coded previously. Cleanup the paintEvent method of VisualizationWidget, e.g. by extracting a method to determine the color to use for the line and by pulling variables to the place where they are used. Fix some Clang warnings.
