 To show an icon on a event just take CtI = Iconid
 as the name of the event.
 Example: CtI = 1
 If you want to set the icon visible just use this in a
 Call Script...
 icon_visibility(id,status)
 id = eventid
 status = true/false
 this command works only for an event on the visited map.
 To change the visibility of all icons on the visited map use:
 all_icon_visibility(status)
 status = true/false
 To change the visibility of all icons on all visited maps use:
 global_icon_visibility(status)
 status = true/false
