PlayerEx

*Fixed loading attributes that were not an instance of ClampedEntityAttribute
*Moved all sound configuration to client side (this means that players on multiplayer can't hear you levelling up)
-Removed particles when levelling up (too extravagant)
+Exposed another API method so that I can fix a bug in RelicEx
+Added client side config options to control the volume of PlayerEx sounds (due to loudness/quietness complaints)
+Incremented version to 2.0.4
