With this PR we optimise a function that is called quite often when loading new cells. We remove avoidable dynamic_casts. We remove an unused pair.second element. We convert a map to an unordered_map because its ordering is irrelevant in this case. We avoid adding the root Skeleton node to the bones' node path.
