#350 CIF/ToolDef metamodel diagram improvements
- Removed import signs on inheritance lines of CIF/ToolDef metamodel diagrams. They somehow were already not in PNG exports. Still, I re-exported them just to be sure.
- For ToolDef, I also removed
position
structural features from the diagrams. I also regenerated the PNG images for that. - I also regenerated the CIF Ecore documentation PDF to include the latest images.
