[Done] Return value for ChangeCurrentElement()

It would be helpful if ChangeCurrentElement() returned 0 on error, and non-zero on success (as it is the case for many other built-in PureBasic functions).

see viewtopic.php?f=13&t=73313

The only way to know if the pointer you passed is valid is to do a ForEach through the entire list to check. That would defeat the purpose of the function.

You must pass a valid pointer. There is no "error" case for this function.
