New function for updating a config section

It is now possible to add new subsections and/or keys to an existing
section. To achieve this, the respective _config_section_update function
must be used to set the new default values.

Returning True in _config_section_update, will mean that the specific
section has been updated and it will be overwritten with the new values.
