imshow.m: Add support for 'parent' property (bug #45473).

* imshow.m: Add cell variable prop_val_args{:} when calling image or imagesc.
Populate prop_val_args with {"parent", hparent} when "parent" argument given
to imshow.  Remove code commented out in 2015/05/1 which has not caused any
problems.  Add warning that arguments "border" and "reduce" are not supported.
