Changeset 2084 for code/branches/objecthierarchy/src/core/Identifier.h

Message:

• Added debug overlay that is constantly shown in graphics mode. F2 toggles its visibility, but only in level mode for now.
• Added ConstructionCallback to get informed about the construction of any object of a specific type. Use RegisterConstructionCallback(ThisClassName, TargetClassName, FunctionName); to register such a callback.
