Impossible to change 'username' field of homebridge config.json

I haven't tried the other fields, but I needed to update mine and there is no way to do so using Homebridge Controller. I must find the file and change it manually.

This could (I suppose) screw things up with the connection (between HomeBridgeController and HomeBridge) since it bases a lot off that info. However, HomeBridgeController we just need to handle that properly 😄
