+4J - Both modifier uuid and name have been replaced by an id enum. Note that we have special value
+"eModifierId_ANONYMOUS" for attribute modifiers that previously didn't have a fixed UUID and are never removed.
+	
+To all intents and purposes anonymous modifiers don't have an ID and so are handled differently in some cases, for instance:
+	1. You can have multiple modifiers with the anonymous ID on a single attribute instance
+	2. Anonymous modifiers can't be removed from attribute instance by ID
+
+IMPORTANT: Saved out to file so don't change order. All new values should be added at the end.
