Added support for float colors (allowing more than 8bit precision colors)
Added a "Set Color 16bit" command to the DMX module
Added a color type enum parameter on both "Set Color" and "Set Color 16bit" command to be able to also send alpha as a value on the DMX ouput or to use the alpha channel as a dimmer for the other colors (multiply)
