Clip: rearrange storage of clip presentation data

Browse source 
This can only be a preliminary solution, since we do not know
the actual usage pattern of the ClipDelegate object yet.
We only know there will typically be a huge amount of clips
to represent in the UI, and we need to be careful to avoid
unneccesary reallocations.

Thus for now we use a data record as base class, and we
move the data record into the new allocation when switching gears.
However, this could easily be converted into a data delegate,
where we'd only transfer ownership without reallocation,
in case this turns out to be more efficient.
