Breaking Lua API changes in fa2eed1

[Ottatop]

fa2eed1 changes all config objects back to config modules, the way they were before the migration to gRPC.

Rationale was that everything looked noisy with : and I'd rather have better visual separation of modules and handles than not have global state.

So if for some reason you're trying to use this thing and you have a custom config you should just be able to replace : with . in the necessary places.
