Send events at module state change

[miklezzzz]

Overview

Following changes:

• Two new module events were added: ModuleStateChanged and ModuleConfig changed;
• Modules got a new state field enabledScriptResults that contains the result of running the enabled script of a module. It comes in handy when we need to know if a module was disabled by its script or something else;
• Modules can "export" their hooks' statuses via a new method;
• Module manager got several new methods which can be used to alter a module and send a relevant event over a notification channel (like setting a module last error and updating hooks' statuses);
• Module manager can be set to use a pre-created notification channel.
