Renaming a Playthrough does not rename the files

• It appears like it deletes all the files, whereas all that has happened is that the playthrough has been divorced from them.
• Any new saves will be under the new playthrough name, ofc.
• Renaming the playthrough back to what it was will 'recover' the original saves, orphaning any new ones.
• Quitting out and restarting before reverting the playthrough name will cause the auto-generation of playthrough names function to recover the files into their original playthrough name, leaving the renamed playthrough in place with its own files (if any)
• Quitting out and restarting after reverting the playthrough, but also after creating new saves in the temporarily renamed playthrough will recover the orphaned saves into their own whatever-you-renamed-it-to playthrough.

My original code would also (since every slot got a default name of PlaythroughName + " " + SlotNumber) replace any instance of PlaythroughName found in the SlotName, also; having a PlaythroughName of Bar doesn't make much sense if all of the slots are still called Foo 1, Foo 2, etc.
