RGB mixer visualization

Dragging and dropping the RGB mixer task in the visualization allows the clients to control the color using bOS Client.

By default, white channel is disabled and only RGB control is allowed.

To enable white channel, select the RGB mixer in the theme in bOS Config and enable white channel.

The client can then select the RGB mixer and either use the color wheel or the sliders in the bottom to control the color.

Separate white channel is the bottom slider. Desired color is visible at the bottom as well.
