Single config per server

[idkfrancis]

Hello, I suggest to use config.js as the default configuration. Each server will have its own configuration via the database and the parameters can be changed from a Discord command. At the moment it's quite problematic because we cannot correctly use "welcomeChannel:" and we cannot change this information via a Discord command.
In advance, thank you for your answer.
I want to thank the devs for this code;)

This bot was never meant to be for multi guilds, so this will not be changed. Sorry.
