-Added a new method in Resource: reset_state , used for reloading the same resource from disk -Added a new cache mode "replace" in ResourceLoader, which reuses existing loaded sub-resources but resets their data from disk (or replaces them if they chaged type) -Because the correct sub-resource paths are always loaded now, this fixes bugs with subresource folding or subresource ordering when saving.
