Rename the private "owners" to "creators" to avoid confusing this with the owner of the track element's memory. Also made the ungroup method for GESClip symmetric by making all the children of the resulting clips share their creators, which allows them to be added to any of the other ungrouped clips. Once the clips are grouped back together, the tracks loose these extra creators.
