Unparenting objects from armatures/curves/lattices now removes the corresponding
modifiers now
This makes it harder for users to unwittingly create multiple deform modifiers
by parenting and unparenting a number of times, with the net result being that
"Clear Parent" is now the true inverse operation of "Make Parent".
