Fix loading saved games from the title splash.

[KevinMoonglow]

Saved games weren't loading from the title splash. This updates the code used by the splash to match up with the load method used by the load command.

🎉 Issues resolved:

• closes #223

🧪 How to Test

1. Load a saved game from the title, before starting a new game.
2. Game should load properly if it was saved to ./saved_stories/, where previously loading from the title would only find them in . (the current directory).
