Every function has now an unique ID-number. This number is used instead of index-number (the position the function had in the two functions-arrays). As the two arrays were converted to two QValueVectors the index-number of a function would be changed when a function with a lower index-number was removed. Therefore, the ID-number is needed to addres a function.
