Removed reduntant plugin name for logs, the log function already adds
the name of the plugin in front of the message.

Replaced string.replaceAll for the proper
ChatColor.translateAlternateColorCode method.

Removed the return from setupChat(). What is the point of returning a
value if it wont be used?

Removed eventCanceled check from onPlayerChat. The @EventHandled is
already set to ignore if the event was cancelled.
