Overview

Adds a listener to the plugin's collection of event listeners. When the named event occurs, the listener will be invoked and be supplied with a table representing that event.

Returns true if the listener was successfully added to the plugin. Returns false if given invalid arguments, such as the listener not being a function or if it's a table that is missing a function matching the event name.
