4.1.0

• Introduced @EventMethod wrapper in both EventThread and any class implementing EventListening. Can now be used to register immutable Event Listener callbacks within the declaration of any class as a var, and invoke the method registerListeners() on the init method of said class to automatically register any @EventMethod-decorated Listener using Reflection.
• Replaced the returning of Tokens (UUIDs) when registering an Event Listener, or an Event Callback (inside EventThread) with an appropriate Handle type, containing a remove() method to unregister said Listener/Callback.
