Previously, if we had children a, b, c, and d, then removed b, the group position for c and d would potentially be marked as dirty, but a would not. This caused the check for the availability of previous group info to return outdated information. This patch now always forces the update of all children's group position when a children move has occurred, since it potentially affects all the children, not just the ones after it. In addition, accGroupInfo::Update() now checks if the previous and next siblings that are being used as shortcuts have dirty group info, and are being used only if they do not.
