SAVEFILE UPDATING/VERSIONING - 'Simplified', or rather, more coder-friendly ~Carn
	This proc checks if the current directory of the savefile S needs updating
	It is to be used by the load_character and load_preferences procs.
	(S.cd=="/" is preferences, S.cd=="/character[integer]" is a character slot, etc)

	if the current directory's version is below SAVEFILE_VERSION_MIN it will simply wipe everything in that directory
	(if we're at root "/" then it'll just wipe the entire savefile, for instance.)

	if its version is below SAVEFILE_VERSION_MAX but above the minimum, it will load data but later call the
	respective update_preferences() or update_character() proc.
	Those procs allow coders to specify format changes so users do not lose their setups and have to redo them again.

	Failing all that, the standard sanity checks are performed. They simply check the data is suitable, reverting to
	initial() values if necessary.
