Option: Colorpicker: send command while still holding finger on colors

[gersilex]

To make it easier to find the right color, it would be nice to have a small optionbox at the bottom of the colorpicker to enable instant color changes.

Default behavior: send HSB Type when releasing finger. This should be kept as default behavior.

Optional behaviour through optionbox:

• send HSB Type if...
  • has been changed (this should be the hook) AND
  • 200ms (to be discussed) have passed since last send

I have a hard time fine-tuning the color when I always have to re-touch (and therefore misplace the selection dot).
