(usability) Possible to break the config from ingame in a way that requires file-editing to fix

[quat1024]

I've seen this tech-support pattern come up a few times:

• edit the config in a way that it crashes when being deserialized (e.g. write capital letters in something that turns into a ResourceLocation)
• press "ok" in the config gui
• game crashes trying to load the config
• restart game
• game crashes trying to load the config (before you can even get to the config screen to fix it)

People who don't know that you can hand-edit TOML files then get stuck and feel like they need to delete Quark to fix it.
