Fixes for unusual story loading circumstances.

This PR does three things when loading a story from within the browser:

1. Prevents an error if a story file is not valid JSON.
2. Catches an error is a file is JSON, but lacks an actions property.
3. Replaces getcwd() and instead uses the path of the script file itself in case someone does not start the app from the current working directory.
