optional types do not get the operators of their non optional counterpart

[jaredlll08]

This script does not work:

 if itemHandler != null {
 println(itemHandler[2].commandString);
 itemHandler.insertItem(1, <item:minecraft:dirt>, false);
 println(itemHandler[1].commandString);
 }

but this one does:

 if itemHandler != null {
 println(itemHandler.getStackInSlot(2).commandString);
 itemHandler.insertItem(1, <item:minecraft:dirt>, false);
 println(itemHandler.getStackInSlot(1).commandString);
 }
