Use Listener instead of the registeredListener

Though i want to change some things in regards to this plugin I do not currently have the time to do so. These small changes are fine and the plugin works fine.

This time I checked and noted that the jar does include the logging of the classpath

This probably works, if not yeah lmk.

That's about it.

You should only listen for the getters of any events to reflect changes in the value behind the curtains.

Added org.slf4j to shaded libraries

Clones values from methods subscribed to, and now offers support for sub events that don't have their own handler.

Fixes a config parsing issue, and allows listening to itemstack changes.

Lesser size, lesser code obscurity

First off, due to a suggestion by a user, you can now listen to all cancellable events by simply tuning the config.yml

Upon the first launch of 0.2, you will also need to redo your old config if you got any.

This update will make the logger consistent instead of using the listener logger.

This also adds another library which fattens up the jar a little more, bear over with it for the features
