* [homematic] Split color and effect support
There are homematic devices (like HmIP-BSL) that support color but
do not support effects.
Split the support, so that color can be supported even if effects are not.
* Make effect fully independent of color
If a device supports effects for e.g. just brightness, it shouldn't be coupled to the color
