Group-clips always send grey as their color

[git-moss]

It seems that the behavior of the group clip color has changed in 2.4. A group clip now displays ALL colors of the sub-track clips in its' right half (which is nice). When you try to set a color for it, simply all sub-clips are colored. So, it seems a group clip does not have a its own color anymore. Therefore, the color() property of the clip always returns grey, which results to grey-pads on Push, Launchpad, etc.

Question is now: What to do about it? Due to the hierarchical navigation of the Push implementation, I do not even have the information about the sub-clip colors. Maybe the property could simply return the color which is most used for the sub-clips? Otherwise for the display it would also be nice to have all colors.
