/*
 * Author: commy2
 * Add an event handler that executes every time the scroll wheel is used. This is needed, because adding a MouseZ display event handler to display 46 will break in save games.
 * _this will be [Interval] where 'Interval' is a number.
 *
 * Arguments:
 * 0: Code to execute <CODE, STRING>
 *
 * Return Value:
 * ID of the event script (used to remove it later). <NUMBER>
 *
 * Public: Yes
