ClusterManagement: improvement towards not having to copy lists

Every keyword which calls ClusterManagement__Given_Or_Internal_Index_List
now receives copied list, so removing items is safe.

Also, empty lists are not considered ${EMPTY} anymore.

Other improvements:

+ Care taken to return sorted lists.
+ Added comments about Beryllium and Boron ownership candidates.
+ Used CompareStream before list copying.
