primitivus: key can be changed in config:
    - new config module manage configuration
    - if any configuration error happen, config parsing is stopped, and a popup appear + a log error
    - key can be changed with key_[action_name] = [shortcut]
    - early popup (popup happening before main widget is built, e.g. in profile manager) are managed
