Currently the settings are read on startup https://github.com/Lea-fish/Leafish/blob/main/src/main.rs#L217 and then passed along through the entire application. This works but is complicated and annoying, you don't want to pass such a global thing around everywhere. It would instead be nice to be able to do settings::get(<setting>) to get the value, from anywhere in the code.

For example settings::get(auth::CL_USERNAME) should return you the username used.

Also currently the settings reading and saving is done inside src/console/mod.rs which seems like the wrong place to do such a thing. Instead that should focus entirely on the console of the game, and let the settings module do it's work itself.
