-----------
Speedup for Grease Pencil animators.
Saving and loading gpencil was using different order for the individual list items.
On a 120 Mb gpencil project (yes, animators!) loading time went down from 1 minute
to a second or two.
Note that this to have effect, you need to save once.
Developer note: check this commit, it uses a new writelist function. You can
speedup stuff tremendously with keeping saved and read data in sync.
