BGE: Committing patch [#31442] "API improvements: Group references python api, for better control over groups and instances" by Martin Sell (moerdn). This patch adds a member and a group property to KX_GameObject:
* KX_GameObject.member returns the list of group members if the object is a group object, otherwise None is returned
* KX_GameObject.group returns the group object that the object belongs to or None if the object is not part of a group
