Guild Chest Fix 1.4.1

Dragging your world folder onto the exe now works, and so does typing the folder at the manual path prompt. Before this the tool only accepted the Level.sav file itself and answered "No file at ..." for anything else, which read like it could not find your save at all. If the folder holds a Level.sav the tool now uses it, and when it does not the message tells you both forms it accepts. Nothing about how the save is edited has changed, the edit is still one number per guild, verified byte by byte, with a backup written first.
