oox smartart, picture strip: handle bitmap fill of pres nodes

There were two problems here:

1) We did not import bitmap fill from presentation nodes.

2) Presentation nodes contained properties with reference semantics, so
if you set a bitmap fill for a first and a second shape, then at the end
both shapes contained the second bitmap.

With this, both bitmaps are imported exactly once.
