Fix for add hook/vertex parent for meshes

The only way to achieve this is to re-load editMesh.
After this commit you can't iterate through vertices and insert
hooks/parents from script anymore -- this operators are now
treated as topology-changing and shouldn't be used when iterating
via geometries.
