Attempting to build for minecraft 1.20, 1.20.1, and 1.20.2. Replacing getLiteralString with getString, for compatibility

Removing API keys from appearing on screen during commands or outputting in log files, for better security.

Fixed permissions on commands, so only help command can be run by all users. All other commands require op (level 4 permission). Also added more debug log output from commands, so it's logged on the server when a command is run.

- Load API url, key, model, and other settings from config file (creaturechat.json)
- Expanded our Config class to include other API settings, such as context length and output length.
- Include 20 generated funny error messages

Updating commands to add optional --config server, or --config default. Also adding configuration handler to actually create and load config files.
