So far, linked IDs were not properly sorted at all, only the ones explicitely linked from WM code would be, but any indirectly linked data-blocks would end up in some random order in their lists. While not ideal, this is not a huge issue in itself, but it had bad side-effects, e.g. causing (recursive) resync of overrides to happen in random order, leading to mismatches between name indices of newly-generated override IDs and the one existings e.g. And in general, it is much better to be consistent here. Note that the file sub-version is bumped for this commit, since some sorting (the directly linked IDs which we keep a reference to) should never need to be re-done after relevant doversion process.
