Object method declaration in joined classes.

[Admins]

Fixed the problem by also adding the script id to the function name. A side effect is that when you update the class script then the original function object is not linking to the new function and is displaying an error, previously it was probably calling a function of the new script which might not be the same.
The fix will be in the next npcserver update, not sure when that will be because it will also require gserver restart.
