Subject: [PATCH] Enable Part_Mirror child item in tree

Part_Mirror now shows its child shape in the tree under
the newly created Mirror Feature. On deletion it's
child shape is set to show (if it had been hidden). Thus
making its behaviour and appearance consistant with other
Part tools, E.G. Part Fillet, Part Loft, etc.
