Resolve issues with Event IgnoreCancelled annotation being ignored

[RhysB]

Ensure the server adhears to the ignoreCancelled (@EventHandler(priority = Event.Priority.Monitor, ignoreCancelled = true)) annotation for listeners.

This code has been tested and verified utilizing the following code.
` @eventhandler(priority = Event.Priority.Monitor, ignoreCancelled = true)
public void monitorChatEvent(PlayerChatEvent event) {
// Print the message to the console with the priority

    if(event.isCancelled()) {
        logger(Level.INFO, "Monitor: " + event.getMessage() + ". This should not be printed as this listener is set to ignore cancelled events.");
    } else {
        logger(Level.INFO, "Monitor: " + event.getMessage());
    }
}

@EventHandler(priority = Event.Priority.Normal, ignoreCancelled = false)
public void normalChatEvent(PlayerChatEvent event) {
    // Print the message to the console with the priority
    logger(Level.INFO, "Normal: " + event.getMessage());

    // 50% chance to cancel the event
    if (Math.random() < 0.5) {
        System.out.println("Cancelling event");
        event.setCancelled(true);
    }
}`
