FLUID: type node placement in scene graph revised

- fixes copy/paste operation that would place pasted types wrong
- improves paste into folded and unfolded groups
- improves duplication of multiple types
- much improved placement of types that don;t fit at the
  requested position
- some more testing will follow in the next days
