Changes this by removing n_removals strings and adding additions to it.
This function is more efficient than [[email protected]] and [[email protected]], because it only emits the items_changed signal once for the change.
This function copies the strings in additions.
The parameters position and n_removals must be correct (ie: position + n_removals
must be less than or equal to the length of the list at the time this function is called).
