Handle object 0 (nothing) gracefully in object parser 
Per the Z-machine spec, object 0 means "nothing" and operations on it
should be safe no-ops: get_child/get_sibling/get_parent return 0,
test_attr returns false, set/clear_attr are no-ops, etc. Previously
these threw ZObjectIllegalObjectNumber, crashing on games like Curses
that pass object 0 to get_child during room transitions.
