Added local save backup.
The game will now create two local backups whenever the game is saved, which makes the save folder look like this:
[b]SAVE.BND[/b]: the save file used by the game and Steam Cloud
[b]SAVE.COPY[/b]: local copy of the SAVE.BND file
[b]SAVE.OLD[/b]: local copy of the old save file
Saves are located at "c:\Users\user\AppData\LocalLow\Graverobber Foundation\Dragon Ruins II\".
If you encounter any issues with your save file (SAVE.BND), try replacing it with one of the local copies (SAVE.COPY or SAVE.OLD).
