To better store instances of manager classes such as FlightHandler, DBCooldownManager, and more to come in the future, an abstract Manager class implementing Listener has added. This class serves to provide easy accessibility of Manager classes without needing to store individual variables everywhere or restoring to solely static classes.
**Usage**
To create a Manager class, simply extend `com.projectkorra.projectkorra.Manager`.
To register your Manager, simply call `Manager.registerManager(Class<? extends Manager>)`.
It is required that your manager has a constructor with no args as this is used to instantiate your class.
It is highly recommended to make this constructor private to prevent new unintentional instances being created.
To get the Manager throughout your code, simply call `Manager.getManager(Class<? extends Manager>)`.
Manager provides two overridable methods, onActivate, and onDeactivate. These methods are called when the Manager is activated and deactivated respectively.
A Manager is activated when `Manager.registerManager(Class<? extends Manager>)` is called, and deactivated when ProjectKorra is disabled on reload/restart.
As Manager implements Listener, any events related to this manager class should be contained within the class.
