Bug Fixes and New QoL Features

I've added the option to import and export save data. Additionally, if you have a paid API key from Cohere you can now take advantage of the much longer context window (128k for paid vs 4k tokens for the trial key).

Bug fixes:

• Loading a save no longer loads old credentials
• Double printing of the intro text on reload fixed.
• In-game error popups for API failures to help users understand what's going wrong.
• Orgone Collector saves filtered out of the save games.
