Previously, the NancyEngine class was responsible for handling creation and destruction of many naked pointers to engine data, which led to several instances of memory leaks that needed to be fixed. These changes introduce a standard way of handling that same data, similar to the one already used by PuzzleData inside Scene. Unfortunately, this does add the need for relevant data to be casted to the proper type before it is handled.
