add color parameter to the knight rider effect

I have created a hyperion plugin for the HomeSeer software (HomeAutomation system). In this pluginI let users create custom effects by changing the parameters of existing effects.
One user asked for the possibility to create the knight rider effect in different colors, so I added the color as a parameter for this effect.
