Subject: Rework group saving

save / saveParent write back to the original group
saveParent saves changes in child groups (openAsChild) by saving the top-most parent
saveAs / saveAsOverwrite resembles the old save / saveOverwrite
For all other saving methods, groups opend with openAsChild are saved as if there was no parent
