    [640] send around 'stopping' messages, and handle them
    
    When closing a ModuleCCSession, a 'i am stopping' message is now sent to the ConfigManager, which in turn informs Cmdctl (which then causes bindctl to update its list).
    
    This causes stopped modules to disappear from bindctl until such time that they are enabled or started again, so that config updates and most importantly, commands, do not cause weird timeouts (bindctl will immediately inform you of modules not running)
