Save Files
* (Fix) Forgot to uncomment out the “Save Containers + Player Blocks” code which had been commented for testing.

Game Items
* (Change) Instead of using a bunch of fields for referencing, used just one as a pointer to whatever kind of class instance it is.

Loading
* (Fix) Containers, Doors and Campfires were not being loaded into the game (well, they were trying, via an old function, looking for a non-existent file).

Player and Game Start Windows
* (Update) When deleting a Player or Game World, removes the new physical data files (when Player deleted, has to remove any child Game World files).
